    this is a problem with the variable cam timing, and you will need to find a mechanic that knows those engines. Most mechanics have never worked on one of those. :-(

We scanned it and it shows code P0025. How do we fix it?


this may help. A code P0025 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0025 DTC specifically refers to the camshaft (cam) timing In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. The "B" camshaft is either the exhaust, right, or rear camshaft. Bank 2 is the side of the engine that does not contain cylinder #1. This code is nearly identical to P0022.
Potential Symptoms Most likely a P0025 DTC will result in one of the following:
  • hard starting
  • poor idle and/or
  • stalling
There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes A P0025 DTC trouble code may be caused by one or more of the following:
  • Incorrect camshaft timing
  • Wiring problems (harness/wiring) in intake timing control valve control solenoid system
  • Continuous oil flow to VCT piston chamber
  • Failed timing valve control solenoid (stuck open)
Possible Solutions The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCT solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

CODE READER SHOWS FAULT CODE P0025


P0025 Generic Exhaust Camshaft Position Timing - Over-Retarded (Bank 2)

This could possibly be a solenoid problem(part of cam timing). Apparantly these sensors get heat soaked and stop communicating with the PCM . The car shuts down, cools off and then will go again.

Could be a number of causes.Some simple some not. Go to autozone and ask them to read your codes for you. They have a code reader they can plug into your car that will tell you what made the light come on.
