Okay so yesterday the ex starts running rough, no power, sucking fuel like crazy. I manage to read the codes and I get what you see in this video.
To me it looks like 118 123 and 11.
118 is Coolant temp sensor voltage too high. The sensor is almost new. I tested the resistance on the sensor at different temps, it's in spec. I check for continuity for both wires to the PCM, they're good. Checked for 5V on the gry/red wire, it's in spec.
123 is TPS voltage too high. Checked for sweeping voltage at varying throttle positions, looks good. Checked for continuity on the wires to PCM and for proper voltage. All looks great!
What else could it be? Either I'm interpreting the codes wrong or bad PCM?
I cleaned all the connectors etc. and cleared the codes. 123 hasn't come back (yet?) but 118 is persistent. After clearing the codes the CEL will come back on within about 15-30 sec. of running.
Thanks in advance for your help!
