For test ecm signal by volt meter can you connect red pole of voltmeter to negative wire (on selenoid) and negative pole on battery and rev car to 2000 rpm and see the voltage fluctuation?
I have this code on driver side but i have zero on one side voltage and 12 something on other wire so connector is ok and ive changed selenoid 4 times and no luck after few restart, Timing chain tensioners and giude done, still same code changed cam shaft sensor and crank sensor and no luck omg what else, yeh ive changed oil and filter and no sucess so what to do?
WAS THAT THE GREEN WIRE OR THE BLUE - ALMOST GOT WHAT I NEEDED , THANKS FOR TRYING - BUT WAS NOT ABLE TO SEE THE WIRES. JUST ONE QUICK TURN OF THE CONNECTED AND I WOULD HAVE SEEN IT.
Jim Caterino Hi so a quick test in VVT variable Valve Timing you can disconnect the solenoid two wire connector and with the ignition switch on engine off tested and look for power and ground in one of the wires you going too have 12. Volt or battery voltage in the other wire is going too have ground... know the ground side is control by the ECM or PCM is inside driver build too control de VVT solenoid! The video you watched in this vehicle the driver was bad the computer have to be replace! And that’s was the Fix...
Thanx, but I get that - I still need to know which wire Should give 12V and Which should be ground in case the wires got switched. Example : looking at the inside of the wired plug (female) Straight on with the connector latch on top - should the White with Green line wire be on the right or left?
Jim Caterino Hi so that's easy to know! Connect a test light to the negative size and disconnect the VVT solenoid turn the Ignition switch to ON engine OFF probe the terminal went the test light illuminate that's your positive! The other is the ground control by the ECM
thanks for video Pete, 2 questions - 1. is the solenoid power switched or ground switched. 2. is the 12 volts ghost voltage or a true 12 volts, cheers sandy
sandy anderson okay if one of the wire from the VT Solenoid have battery voltage KOEO key On engine Off that's means the PCM or ECM control this Solenoid by Ground what they call in the technical terms a pull to ground or pull down design! Know because this signal is so fast you have to see it with a scope or Snap On Computer safe Test light and also a bi-directional Scanner too command the signal! Hope this information helps you!
Pro STEEZ The ground for the VVT are supply by the ECM engine control module... in this particular case was a bad ECM replaced and programmed and you are done!
Ryan Dooley listen 👂 too the words! The garage change the timing change! Then this problem comes up! So my work is to find out way! And I did! The ground control for the VVT solenoid was bad... bad driver...
Gilberto Perez yes was the PCM I test the wires near the solenoid and it fail the test what is not in the video is the test on the PCM pin connector! And that fails ...replace the PCM or ECM Flashed and fix the problem...
Gilberto Perez okay another thing to make sure in the bank 1 is the the harness connector ... You have to check it and make sure the pin terminals are clean ... That harness connector supply power and ground to the two solenoid...
