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.
