List of fault codes! Help!
Hello,
So other than the dreaded “anti skid service” message (still not a clue how to fix this) I did a scan today on codes. P0123 - TPS circuit high P0222 - TPS circuit low P0335 - crankshaft position sensor circuit P1412 - unknown code Could anyone shed some light on what could be wrong here? I cleared all faults - none have come back yet, other than the anti skid now and then. Also, there is a feeling of a dip in power now and then. As if someone is dabbing the brakes lightly (usually when pedal is at a certain position) this is also joined by temporary limp mode (no longer than 15 seconds) I want to get this sorted but don’t know where to start! I’ve cleaned all contacts on the fuse box under the passenger side dash. What to try next? |

First job will be to Google the individual codes.
They're generic OBD2 codes so will be easy to find.

Hi there , the first two codes refer to the throttle position sensors , most probably wear / dirt on contact faces . Normally the switches are sealed & hard to get at
The crank sensor may be slowly giving up its will to live or simply have a build up of oily rubbish over the very end of the sensor , stopping it from providing the ECU with a stable signal AND FINALLY ! P1412 EGR Different.Pressure Sensor Signal too Low hope these help

Thanks all!
I’m trying to locate the TPS, to give it a clean. Does anyone know where it’s located? |

It is usual to have two TPS one under / attached to the Loud pedal & normally sealed in a plastic housing . The other is in the throttle body and even more difficult to get at .
You can use a live data reader to see which sensor is misbehaving , at a push an multimeter can be used . You are looking for a sudden drop or large increase in the resistance values as you SMOOTHLY operate the pedal
