engine umber MXS37085
active code: eng sht hi 128 129 03
Thanks for the information.
I'm sorry. Code 129-03 is not on the code list for an MXS engine. I must assume that code is for something else.
One thing we can do is try and pull the flash codes from the engine ECM. If you have never done this. Here is how.
Use the following procedure to retrieve the flash codes from the check engine light:
1. Turn the ignition key switch to the On position/ Engine OFF.
2. Turn the cruise control ON/OFF switch to the OFF position.
3. Move the SET/RESUME switch to either position. Hold that position until the yellow lamp begins to flash.
The yellow lamp will flash in order to indicate a two digit flash code and the SET/RESUME switch may be released. The sequence of flashes represents the system diagnostic message. Count the first sequence of flashes in order to determine the first digit of the flash code. After a two second pause, the second sequence of flashes will identify the second digit of the flash code.
Any additional flash codes will follow after a pause. These codes will be displayed in the same manner. Flash Code 55 indicates that No Detected Faults have occurred since the ignition key switch has been turned to the ON position.
Code 95 indicates there is a fault with the Intake Valve Actuation Oil Pressure sensor circuit. I have seen this before. The most likely cause of this code is a faulty sensor. The Intake Valve Actuation Oil Pressure Sensor is located on top of the engine near the front. It has three wires. I would inspect the harness and make sure it is OK. If it is, I would change the sensor.
Please let me know if you need more help or have more questions.
my driver can't see the sensor can you please give me more detailed info on where that is. is that located near the radiator thermostat or ac compressor?
Sure no problem.
It is right beside the thermostat housing. If he follows the top rad hose to the top of the engine. He will see the 3 wire sensor behind the thermostat housing. It's in from of the turbo right on top of the engine.
thank you very much for your help. We will try to fix the problem asap.
