Hello HMCAC 300. Several months ago I contacted you about the TCL lights coming on and off. I continue to have the same problem, and now it turns and car on and off, even when I am driving. So, yesterday I scan the car for possible problems again. This is the result and I need your help, please. This the code P1102 - Traction Control Ventilation Solenoid Circuit, which indicates that with the engine running for a predetermined period of time the PCM detected the T/C ventilation solenoid motor failed the Comprehensive Component Monitor rationality test.
The Code went further to tell me that: The Traction Control Diagnostic Trouble Code 72 or 73, "Vacuum/Ventilation Control Solenoid Circuit System"may set and the TCL light may come on, due to excessive ignition signal interference affecting the voltage in the TCL solenoid valve harness. This may also cause MFI DTC P1101 or P1102 to set in the PCM. To eliminate this condition, install a noise filter in the wiring harness at the distributor connector.
