Re: GEARBOX DIAGNOSTIC CODES FOR FORD MONDEO AUTO 2002
All eobd codes starting with p zero have standard meanings irespective of model or make PO12 CODE CAMSHAFT POSITION (cmp) intake/front,bank 1 timing over ******
possible cause valve timing engine macanical fault cmp acutator
POO36 CODE HEATED OXGEN SENSOR HO2S)2BANK 1, HEATER
CAUSE FAULTY SENSOR WIREING SHORTING TO EARTH EC
PO59 HEATED OXGEN SENSOR (HO2S) BANK 2, HEATER RESISTANCE
THESE FAULT CODES HAVE BEEN OBTAINED FROM AN AUTO DATA DISC
I HOPE THIS IS OF SOME HELP TRY CLEARING THE CODES AND SEE IF THEY RE APEAR
IF THEY DO THE SENSORS AND WIRING NEED CHECKING

Tech Code "dtc P0014" 2003 Trailblazer - posted in Chevy ... it had been serviced before for the same thing in 2003 or 2004! ... replace the camshaft actuator solenoid, change the engine oil and .... The extended war. co. prob. would not be to happy since they already fixed the sensor once or twice already.
Is it getting gas to the cylinders , is there spark at the spark plugs ! You should check thing's out before replacing parts an hoping it fix's the problem .You need to find out what is missing ,fuel ,ignition or an engine problem ! Cranking No Start Real Time Diagnosis Ford Focus
Code 25 is a problem with cam timing, and code 36 is for a problem with the heater circuit for the O2 sensor - bank one sensor two. The testing procedure for each code would need to be followed to find the problem. You would need a shop manual to get the testing procedure. The codes are not related and the problems may not be constant.
Diagnostic Test Code (DTC) P0013 is "Exhaust Cam Position (CMP) Actuator Solenoid Control Circuit" Diagnostic Test Code (DTC) P0014 is "Exhaust Cam Position (CMP) System Performance"
DTC P0014 can be caused by several things that can affect your variable cam timing system performance including using the wrong viscosity engine oil. However, since you have the DTC P0013, it is pretty obvious that the problem is being caused by a circuit malfunction in the control solenoid circuit. It could be as simple as a loose connection at the solenoid electrical connector. It could be that the solenoid itself has an open circuit in its coil windings, or it could even be caused by squirrels or mice chewing on the wiring harnesses in your engine compartment. You must diagnose the circuit to find the cause. Fixing the control solenoid circuit will most likely make both of these codes go away.
P0012 - "A" Camshaft Position - Timing Over-******** (Bank 1) OBD-II DTC Trouble Code Description
"A" Camshaft Position - Timing Over-******** (Bank 1) What does that mean?
A code P0012 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 P0012 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-********, the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. Potential Symptoms
Most likely a P0012 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 P0012 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)
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 P0012 - Variable Camshaft Timing Over Retarded - Bank 1
How does a P0012 code trigger the check engine light? This code will trigger the check engine light under the following condition: * The comprehensive component monitor, referred to as the CCM, monitors the Variable Camshaft Timing (VCT) position for over-retarded cam timing. If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, the check engine light will come on and set this trouble code.
Possible Causes: Incorrect camshaft timing VCT solenoid valve stuck open or continuous oil flow to piston chamber Camshaft advance mechanism binding, or faulty VCT unit
Diagnostic Help: This check engine light code is caused by a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Possible symptoms may include rough idle, stall or hard start. Refer to manufacturer specific component tests for the VCT unit. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instructions.
Other details mentioned a P0012 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.
