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 as described in this bulletin.
