Diagnosis and Repair:
1 Faulty intake manifold temperature sensor connections
a Inspect the intake manifold temperature sensor and the harness connector pins.
a Disconnect the engine harness connector from the intake manifold temperature sensor.
b Inspect for corroded pins, bent or broken pins, pushed back or expanded pins.
c Inspect for evidence of moisture in or on the connector.
d Inspect for missing or damaged connector seals.
e Inspect for dirt or debris in or on the connector pins.
2 Faulty intake manifold temperature sensor
a Check the resistance of the sensor
a Disconnect the engine harness connector from the intake manifold temperature sensor.
b Measure the resistance between the intake manifold temperature signal pin and the intake manifold temperature return pin.
c Refer to the troubleshooting and repair manual for the specific engine platform for intake manifold temperature ranges.
3 Faulty engine harness
a Inspect the engine harness and the extension harness connector pins.
a Disconnect the engine harness from the extension harness.
b Inspect for corroded pins, bent or broken pins, pushed back or expanded pins.
c Inspect for evidence of moisture in or on the connector.
d Inspect for missing or damaged connector seals.
e Inspect for dirt or debris in or on the connector pins.
b Check for a short circuit from pin to pin.
a Disconnect the engine harness connector from the extension harness.
b Disconnect the engine harness from the intake manifold temperature sensor.
c Disconnect the engine harness from all sensors that have a shared return with the intake manifold temperature sensor.
d Measure the resistance from the intake manifold temperature return pin on the engine harness inline connector to all other pins in the engine harness inline connector.
e Measure the resistance from the intake manifold temperature signal pin on the engine harness inline connector to all other pins in the engine harness inline connector.
f If all measurements are greater than 100k Ohms, then the resistance is correct.
c Check for an open circuit.
a Disconnect the engine harness connector from the extension harness.
b Disconnect the engine harness from the intake manifold
c Measure the resistance from the intake manifold temperature return pin on the engine harness inline connector to the intake manifold temperature return pin at the engine harness sensor connector.
d Measure the resistance from the intake manifold temperature signal pin on the engine harness inline connector to the intake manifold temperature signal pin at then engine harness sensor connector.
e If the measurement is less than 10 ohms, then the resistance is correct.
4 Faulty extension harness
a Inspect the extension harness.
a Inspect for corroded pins, bent or broken pins, pushed back or expanded pins.

b Check for an open circuit.
a Disconnect the extension harness from the engine harness.
b Measure the resistance from the intake manifold temperature return pin on the extension harness connector to the intake manifold temperature return pin at the extension harness inline connector.
c Measure the resistance from the intake manifold temperature signal pin on the extension harness connector to the intake manifold temperature signal pin at then engine harness inline connector.
d If the measurement is less than 10 ohms, then the resistance is correct.
c Check for a short circuit from pin to pin.
a Disconnect the extension harness from the engine harness.
b Measure the resistance from the intake manifold temperature return pin on the extension harness connector to all other pins in the extension harness connector.
c Measure the resistance from the intake manifold temperature signal pin on the extension harness connector to all other pins in the extension harness connector.
d If all measurements are greater than 100k ohms, then the resistance is correct.
