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.
With the DRBIIIt, 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.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
2 Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (A23) TIP Signal circuit and the (K6) 5 Volt
Supply circuit in the TIP Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the (A23) TIP Signal circuit for a short to the (K6) 5 Volt
Supply circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 3
