Car just threw a code 42 when I drove it today, the only thing I've done is change the plugs (2 weeks ago.) &
installed new pads & rotors yesterday...
Trouble Code 42 indicates that there may be a malfunction in the Electronic Spark Timing (EST) system.
Typical causes for this code include:
1) BYPASS line is open or grounded
2) EST line is open or grounded
3) PROM or CALPACK not seated properly in the ECM
4) Poor connections between ignition module and ECM
5) Poor routing of EST harness and/or poor quality ignition wires (EMI induced electrical noise)
6) Faulty or incorrect ignition module
7) Faulty ECM
Which tells me not a lot
Where do I start checking!?!
TIA
