Hi peter,P2135 means Throttle/Pedal Position Sensor/Switch "A" / "B" Voltage Correlation ,read more:Diagnostic Trouble Code Table .

the bcm or something about it has been changed there is a scan tool
that can fix this, thats the only way i know to deal with it

Code 12 doesn't need fixed. When you begin to test codes you will get the code 12 but that is just telling you that it is in diagnostic mode, it will flash the code 12 three times, then after that it will flash all stored trouble codes. After all stored trouble codes have been displayed, the ECM will repeat the process( so getting code 12 again means you have reached the end of the stored codes list) If it displays code 12 three times and then displays code 12 again , it means you have no problem codes.

That means trouble with the manifold pressure sensor, which causes trouble with injection and ignition timing. See here p372

If it's the check engine light, then no one will know what it means till you have the engine computer scanned with a code reader to get the trouble codes.

If the light comes on when engine is running, it means the computer has detected a fault in it's engine management. It will turn on the light and set a trouble code for the fault in its memory. A technician will use the trouble code to diagnose and fix the problem. Depending on the problem, sometimes it's simple, sometimes more complex.
If your car is a '96 or newer model, Autozone (and maybe other parts stores) will do an engine computer scan for free. Cars built before '96 use a different diagnostics program, but code readers for any year car are available and relatively inexpensive at any parts store or at outlets like Walmart. Good luck.

Hi there:This code is for the fuel pressure control solenoid, the solenoid could caus all the codes so I suggest checking it firts. To test..- Remove the PRC solenoid valve.- Check for air flow between ports of the solenoid valve.- If not as specified, replace the PRC solenoid valve.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

what you could start with is checking to see what trouble codes are being logged for this vehicle...if the engine light stays on, it means the ecu is registering a fault......by the means of a trouble code...now the trouble code doesnt tell you how to fix it, but it does give you the direction to go down...judst wondering if you have tried to obtain the trouble codes
