Symptom: P1190-TIP SENSOR CIRCUIT HIGH When Monitored and Set Condition: P1190-TIP SENSOR CIRCUIT HIGH When Monitored: Ignition on. TP sensor voltage less than 1.2 volts. Battery voltage greater than 10 volts. Set Condition: The TIP signal voltage is greater than 4.92 volts for 1.7 seconds. One trip Fault. POSSIBLE CAUSES TIP SENSOR VOLTAGE ABOVE 4.9 VOLTS (A23) TIP SIGNAL CIRCUIT SHORTED TO (K6) 5 VOLT SUPPLY CIRCUIT (A23) TIP SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE TIP SENSOR INTERNAL FAILURE (K153) TIP SIGNAL CIRCUIT OPEN (K167) SENSOR GROUND CIRCUIT OPEN PCM TEST ACTION APPLICABILITY 1 Start the engine. t, read the TIP Sensor voltage. Is the voltage above 4.9 volts? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION symptom in the Driveability category. 2 Turn the ignition off. All Yes → Repair the (A23) TIP Signal circuit for a short to the (K6) 5 Volt Supply circuit. No → Go To 3 269 DRIVEABILITY - NGC |
