Default Optispark Wire Harness

Hey All,

Its been a while since Ive been on here. I did an optispark replacement back about 6 months along with crank shaft sensor. I still keep getting codes for it and was wondering if it was because I purchased the incorrect wiring harness? I had to modify it by removing one of the plastic guide rails.


The code I keep getting is P0335 - Crankshaft Position Sensor A Circuit Malfunction

Other codes Im getting are
P0400 - Exhaust Gas Recirculation Flow Malfunction
P0161 OBD-II Trouble Code


Any help would be appreciated. The car is running fine with no stumble or stalling issues. I would love to fix these issues.

Thanks

Scott
