Apparently there is an issue with some 5spd equipped SS's. Had the check engine light come on 3 different times during the first 1500miles. It went out the first time. The second time the car wouldn't restart, but had all electronics and battery power. Was in a week and a clutch sensor was replaced. Took er home 3 days ago and check engine light came on again today. Took er back and they said the code was still something to do with the 5spd combined with the SS package. Dunno what's up this time, but will let you know when I find out.

Condition
Some customers may comment on Malfunction Indicator Lamp (MIL), Check Engine Light Illumination. Typically, there will be no driveability symptoms or engine performance concerns.

Upon further investigation, one or more of the following DTCs may be stored in the ECM:

• DTC P0096: Intake Air Temperature (IAT) Sensor 2 Performance

• DTC P0335: Crankshaft Position (CKP) Sensor Circuit

• DTC P0806: Clutch Pedal Position (CPP) Sensor Circuit Performance

• DTC P2199: Intake Air Temperature (IAT) Sensor 1-2 Correlation

• DTC P2261: Turbocharger Bypass Valve Stuck Closed

Correction
If routine diagnosis using SI does not reveal any obvious cause, Do Not replace the following components :

• Intake Air Temperature (IAT) Sensor for DTC P0096 or P2199

• Crankshaft Sensor for DTC P0335

• Clutch Pedal Position (CPP) Sensor for P0806

• Turbocharger Bypass Valve for DTC P2261

Important: Verify that the 12-volt battery has a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only use approved Midtronics 165-PCS charger or equivalent to maintain proper battery voltage during programming.

Important: Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen. The J2534 MDI will reprogram the modules in less time than the Tech 2® scan tool.

Reprogram the ECM using the latest calibration if the above concern is encountered. A revised engine calibration has been developed to address these issues. Reprogram the ECM with the latest software calibration. The service calibration is available on TIS2WEB using the Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software version.

I had CEL and reduced power on mine. The above is what he tech used to fix mine. It was the intake temp.
He also noted on the pre-test drive "plenty of power".

Thanks for the help, it turns out it was the clutch position sensor performance P0806, they apparently replaced it last time and now they said it is okay this time.....they needed to reprogram the new one? Seems like something you should do the first time.

Thanks again.....can't pick er up till Tuesday, will let you know specifics when I get er back

Scrivs

Got er back yesterday....ok so far......will let you know via probs/service posts if any issues arise
