I had my truck (2002 chevy 1 ton, duramax, w/ Allison trans) put on a computer and received the following readings:
1.) PO843 - Voltage signal from transmission fluid pressure sensor/switch 'A' too high for current operating conditions.
2.) PO540 - Malfunction exists in electrical curcuit for intake air heater.
Can you guys tell me what these readings mean, and what i need to do to fix 'em.
Thanks,
Shad
