You can clean the MAP sensor just like the MAF, and with the same stuff. Do them every oil change, when you change your air filter. A little regular maintenance can save you a LOT of money in the long run - better mileage, fewer major repairs...
Def don't let it go under 1/4 tank! The fuel helps keep the pump cool and extend its life. I recently replaced the pump in my Trans Am, it lasted 157K miles.
Evie Longoria ,I'm not a mechanic but if the code scanner reads a map sensor problem I suggest you change it.i hope this solved your issue and let me know if you fixed your trailblazer .
mi envoy tenia el mismo problema, incluso otros mas graves que se derivan de ese mismo sensor, lo compre, lo cambie y no funciono, tuve que limpiar todooo el sisema de admisión, desde la garganta, hasta inyectores. camionetas muy bonitas, pero algo delicadas, saludos desde tijuana mexico zacatecano...
Hola Enrique , lo siento por el problema que Tiene Tu troca,pero si Tu envoy Tiene la luz de servicio prendida deverias de ponerle el scanner de codigo para que Te desengañes de Los problemas que tiene Tu envoy .Espero que encuentres la solucion amigo y Saludos .
+MrZACATECANO100 si, de echo me salio el mismo problema que y codigo que a ti, cambie el MAP sensor y no funciono, fue por eso que tube que cambiar empaque de araña de admisión(donde se pone el sensor) limpiar todaaaa esa parte, la garganta estaba carbonizada, y los inyectores igual, no salio caro, pero el trabajo fue mucho, fue una inversion de 550 mexican dolars jeje como unos 40 dolares y quedo como nueva mi envoy, recomendia lo mismo para la tuya, es muy muy bueno hacerle el mismo servicio que yo le hise a la mia por lo menos una vez al año y prologa la vida del motor y mucho ahorro en gasolina
Shatti Unique map sensor was not working ,that's why it didn't pass smog check inspection. Throttle body was so dirty that I couldn't use AC or it'll start loosing power that truck would even turn off.
Shaun Seibles for the AC issue, I cleaned the throttle body and it solved the problem.throttle body gets dirty by time to time ,that is what causes Trailblazer to turn off when AC is on. A dirty throttle body also causes loss of power and wastes more gas. Here's a link to a video when I cleaned it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Hjb5tHKk5u8.html
Que onda compa, my babe didn't pass the test as well for this code too, my tb also vibrates when I accelerate and at times it's slow to accelerate because of this, what do you think it could be?
Super Vegeta well for this code is absolutely the MAP Sensor. For the vibration of it doesn't go away then it's something else .Mine was vibrating when it used to hit 60/65 mph only due to misfire on one of the ignition coils.have you ever changed the fuel filter?
Ey compa tengo una traiblazer pero cuando esta en parking acelera muy suave y el RPM nomas apenas y pasa de 3 y no se ke le pasa porque no marca ningun codigo no hace nada y corre bien
No le e checado nada nadamas le pusieron el scaner pero no marca ningun codigo pero lo raro es que corre bien corre muy fuerte con el A/C encendido pero cuando esta parkeada no acelera pareciera que no tuviera fuerza se oye muy debil
Uriel Vasquez limpia el throttle body , puede que sea eso con el tiempo se tapa de carbón y no deja que pase aire al motor. Aveces se acelera o desacelera. Desconecta la batería antes de limpiarlo.espero que esto sea el problema.deja me saber si funciono.suerte..

Tengo una trail blazer 2002 depronto no quiso arrancar, no da marcha ni nada de señas de arranque, al parecer es el sensor del sigueñal alguien puede ayudarme.
ive been getting the code error p0105 for a while now it comes up as a manifold absolute pressure or barometric circuit ive chance the map sensor once from a part from o rileys it wasnt the ac delco brand it was just some other brand and ive been having my check engine light turn on and off by itself when its on its on for like 3 days then turns its self off ive taken it to a shop and they said they dont know why its going off when i already put in a new map sensor and its been a couple of weeks since then and it still turns on and off i took it to another shop and they told me try to use the oem ac delco map sensor this time just installed it hopefully it fixes the problem if not they said i might have to replace the manifold
MrZACATECANO100 no I haven't tried that yet I thought once u replaced it it would read the code off by disconnecting the battery do u mean disconnecting the positive and negative ?
zamora6090 in the vídeo at 4:07 when I turn on truck the service engine light stays on, and once I disconnected the battery And reconnected again it goes away. It never turned on again after that.
MrZACATECANO100 yea I saw that and just positive first? I took it to a shop today and they scanned it and it turned off and I just replaced the map sensor should I wait until the light turns on again or just disconnected it now since I just change the map sensor
I can’t stand trailblazers my sister had one they fuckin suck I always talk shit cuz I have the gmc envoy drives 10 times better more luxury the tranny engine life is far more extended the envoy all around is by far a better suv but yeah still mostly the same chassis frame all that stuff
