Suffering a poor idle or generally rough running? EML on? reading code P0106/7/8?? This indicates a problem with MAP sensor (Manifold Absolute Pressure). All cars suffer from getting the MAP sensor dirty to a greater or lesser extent (especially diesel) and this causes inaccurate reading which leads to poor fuelling and poor running. MAP sensors can be pricey so always worth giving them a clean first, see if that cures the problem. It'll take less than half an hour and cost virtually nothing.

Some people refer to the MAP sensor as a "boost sensor". In this instance a boost sensor is a MAP sensor. The only difference is that on a forced induction engine, the MAP (boost) sensor needs to be able to read the amount of boost so will need at least a 2bar range. On a normally asperated engine the MAP only needs a 1bar range, since it never needs to measure anything higher than atmospheric (barometric) pressure. HTH.

@randyeastman4500 5 лет назад

does my 99 saab 95 have a map sensor and where is it located if so?

@CycloneCyd 5 лет назад

@@randyeastman4500 Hi Randy, sorry about the delay. yes, it will have a MAP - all FI engines have a MAP sensor. It'll be on the inlet manifold somewhere - though 90s Rovers with MEMS did have them board mounted in the ECU.

@MrLawandorderman 4 года назад

Generally what sensors should be cleaned periodically? I’m a “back yard” mechanic and turned up my sister’s Ford Taurus and I think there were three I cleaned and it made a big difference. An air idle, the map which had some other sensor incorporated and the third might not have been a sensor but managed the vacuum. I would love to know if it made sense with my Saab or my wife’s 06 Lexus sc430. That’s three different engine strategies, Ford - Saab - Lexus. (I also have a Ford truck)

@endurofan9854 3 года назад

the one that manage the vacuum you said was the MAP sensor (manifold absolute pressure sensor) the one with a pin with ball at the edge is tha MAF sensor (mass air flow) the one measuring the flow of air, the're link together to control fuel distribution accordingly along with the oxygen sensor at the exhaust pipe

@CycloneCyd 4 года назад

The REALLY important bit is "leaves no residue". Other than that, it really doesn't matter too much what you use - no pure solvent mixes are going to damage the rare-earth metal and ceramic s of the MAF as long as you don't touch them.

Brake cleaner has solvents that can degrade plastic and rubber. After some time the bonds in plastic polymers brake and it forms cracks.

@@CycloneCyd I don't know the actual ingredients that are harmful, but everywhere I read, people tell about discolored, dull or even melted plastic from Brake or Carb cleaner.

This has the consequence that the rubber will appear unchanged at first; however, it will become brittle, and after a few weeks to months cracks and fractures appear. "

I’ve traveled a lot and haven’t seen 10%. Two favorite places, Savanna, GA and Bisbee, AZ. Never been to England but it’s number 1 on our list. The closest I’ve come is Prague, the pub across from our hotel was owned by a British ex-pat. The only place that served more than one beer. We ended up there every night for 10 days, he assured me it was as close to a British pub as we’d find outside of the UK. It was our favorite part of our day, to get pissed and talk world politics with a Brit.

@asherq8646 4 года назад

This is more commonly found in boosted engines. However, some Honda’s and other makes did include map sensors as opposed to maf sensors for a number of years. A faulty MAF or MAP sensor will cause rough/uneven idling, poor engine response, acceleration, fuel economy, and trouble starting up.

@warnacokelat 3 года назад

Different manufacturers have different ingredients for their brake cleaner/throttle cleaner. For example, a cheap china brand throttle cleaner contains methylene chloride that are known to cause severe chemical attack on many type of plastics. However, other factor such as temperature, concentration and exposure time also plays a role on how the chemical will react with the plastic parts. I think using brake cleaner to clean MAP sensor can damage the sensor, but since nobody cleans their MAP sensor everyday, it would probably be a relatively safe method. But the risk is always there and you never know when will you get unlucky.

I got a bad turbo boost and uneven throttling above 2000 rpm on My SAAB 9-3 TIDD (Z19DTR engine). The Turbo meter on the dashboard does only on the most of the time only boost only half way then under more load the boost get lost or gets uneven. Engine lamp is on while driving. The Fault code I got is P0105 (P0105 52) and is also related to the absolute intake senor (MAP sensor). I removed it from the engine and it was very dirty. Tomorrow I will clean it and reinstall and remove the code and see if this solves the issue.

@synthostyle Год назад

The cleaning was making not that much to the issue. But it was very dirty and clogged up with soot.

@synthostyle Год назад

Another update is that I also had two ECM faulty codes P0671 08 and P06173 08 as well related to the glow plugs for Cylinder 1 & 4 are bad. This probably make the engine making more soot since the combustion will the MAP to clogged up?

@synthostyle Год назад

Update today "check motor" icon on the dashboard have turned off and there is not hesitation or uneven idling. While driving there is not hesitation or lost of boost over 2000 rpm on 3 rd to 6 th gear. I change all the Glow plugs along with the MAP sensor. Nice that he engine is now running better and there is also not that much of diesel smell when the engine is started. I measure the resistance on the old glow plugs, there was one that had around 200 ohm and one was about 24 ohm. The rest two glow plugs had a resistance around 1 ohm (up to 6 ohm is fine/ok value). I was also checking the throttle body by removing the inlet air hose it look alright, didn't seems that much of sot in the throttle body. But it seems that I need to change the battery, I had it for about four years but after about 2 days without driving the car it won't start.

@patterdalezipsuzilil 4 года назад

It's not dirtt it's the recirculation of exhaust gases by the egr valve or turbo burning oil and feeding it into the intake manifold

@CycloneCyd 4 года назад

ALL engines do this to a greater or lesser extent. It's the recirculation of bypass gases and combustion products coming from the crankcase via the PCV whether there is an EGR or not. Burning oil makes it worse, but a dirty MAP is not a sign of oil burning in itself.

@gtaseed 4 года назад

The recirculated gasses from the EGR come in after the sensor, at least on my AVF passat, the sensor mostly gets clogged by dust that makes past the air filter combined with the oil that the turbo slowly leaks + pcv gasses, in time they get a thin cover of sticky junk, just had mine cleaned with isopropyl, worked a charm.

Hi cyd. Im getting a lot of stalling and have po101 coming on. It will occasionally go limp but then ok again. Could this potentially be a mass airflow sensor problem?

@CycloneCyd Год назад

You don't say what car you have or it's age, but if you're doing your own maintence I'm guessing it's not too new. With a P0101 code, I'd be looking for a vacuum leak. That could be any leak into the induction system after the MAF, so check everything for possible splits. You may have more than one leak, Small vacuum hoses can be difficult to check and so you might be better off simply replacing all the small vac hoses with silicone tube s.click.aliexpress.com/e/_DDG1dYT . Larger intake pipes (after the MAF) made of plastic rather than rubber will defo be suspect (see my Saab 9-3 cobra video for an example). Have you tried cleaning the MAF? WD40 contact cleaner is good. Brake cleaner is fine too. Also unplug and replug all connectors to wipe contacts.

Hi there. Would you know if a 2009 Nissan Altima has this MAP sensor, if so where's it located at?

@CycloneCyd 4 года назад

Plenty of engines do not have a MAF sensor, but I've yet to come across one that does not have a MAP. It will be on the inlet manifold somewhere, not far from the throttle body.

I wouldn’t use brake cleaner you realise it is a sensor they can easily brake. I’d use maf cleaner or at worst electronic cleaner

@CycloneCyd 4 года назад

What is important here is not so much the name given to the cleaner (marketing mostly), but that the cleaner you use contains no oils or other chemicals and *leaves no residue.* As mentioned many carb and contact cleaners do leave residue. Brake cleaner is the only one out there that *_never_* leaves a residue.. It won't harm the sensor in the slightest - rare earth metals and ceramics are tough.

Can you help me about seat leon 1.6 16v mk1 petrol, i had engine idle problems, and check engine light is on with EPC light together, i don't know what to do.. I cleaned throttle valve, but no effect. Please help me. Thanks a lot.!

1. have you cleaned your MAF and MAP sensors? This video for MAP and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-V6fxxprx1F8.html for MAF. 1a. if your throttle position sensor/motor unit is one that can be opened, check for oil contamination of the sensor pot and motor. 2. check the PCV system is clear and working 3. check condition of all pipes and for vacuum leaks 4. check all electrical connections and harnessing are sound to the engine ECU, throttle body and throttle pedal. 5. check brake lights work correctly and wires and connection to the brake light switch. This is all basic stuff that should be done periodically anyway, but rarely is. If this yields no result, have the MiL DTCs read.

Never use brake cleaner or carburetor cleaner. Leaves a residue. Use the right cleaners.

@CycloneCyd Год назад

Brake cleaner leaves no residue and neither do most carb cleaners. Check the tin or website for each individual product.

isnt that a MAF sensor? mass air flow sensor... map sensor meassures the vacuum i saw a pin like thing at the middle wich is what was n the MAF sensor that measures the flow of air

@CycloneCyd 3 года назад

Nope, it's a MAP (manifold absolute pressure) sensor. A MAF is usually a 'hot wire' sensor. www.densoproducts.com/map-vs-maf-whats-the-difference

@mac4boys541 3 года назад

And it has a temperature reader, the small bulb in the centre at 1.28

@1964Cobo Год назад

Dont use brake cleaner. Best way to clean is electro contact cleaner. Dont spray directly to sensor as this guy did, since you can damage membrane that is esential part of the sensor.

Thanx very much for the video i just just to ask where can i find the MAP sensor on my car’s motor ( misubishi grandis 2,0 did diesel Audi motor ) thanx again

@CycloneCyd 4 года назад

don't know on that motor, but it shouldn't be hard to find. It's usually on the inlet manifold somewhere

Never ever use brake cleaner on that sensor only carburetor cleaner

Hi can you use brake cleaner to wash the MAF sensor as well (the sensor right after the air filter) ?

@CycloneCyd 5 лет назад

Yes you can. Indeed, I do. See here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-V6fxxprx1F8.html

@xinixxagnix201 5 лет назад

No way, you need CRC Mass Air Flow cleaner for the ''MAF'' Never use brake cleaner, it will destroy the MAF ;)

@CycloneCyd 5 лет назад

@@xinixxagnix201 NO it won't. MAFs are made of metal wires (platinum mainly) and ceramics (some even have a glass film coating). So, please explain how a cleaning solvent will wreck this??

@LDantinhas 5 лет назад

Cyclone Cyd he thinks it’s made of sugar spice and everything nice, so you must use a spray of soft sugar from heaven made of angel clouds 🤣

@ohboy2592 4 года назад

You can use any cleaner that doesn’t leave any residue. Some cleaners leave a residue and that can destroy your sensor if it’s a hot wire sensor. The residue will get too hot on the sensor. All MAF cleaners are residue free. Certain brake cleaners are residue free and some are not.
