PINPOINT TEST G531332p13 : ENGINE OIL TEMPERATURE (EOT) SENSOR RANGE/PERFORMANCE, HIGH/LOW VOLTAGE

G531332t45 : CHECK THE EOT SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Key off.
2. Disconnect the EOT sensor electrical connector, PI24.
3. Disconnect the ECM electrical connector, PI300.
4. Measure the resistance between:

EOT sensor connector PI24, ECM connector PI300,
harness side harness side
Pin 02 Pin 23

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G531332t46.

G531332t46 : CHECK THE EOT SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO POWER
1. Key on, engine off.
2. Measure the voltage between:

EOT sensor connector PI24, Battery
harness side
Pin 02 Negative terminal

- Is the voltage greater than 3 volts?

->YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G531332t47.

G531332t47 : CHECK THE EOT SENSOR SENSING CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Key off.
2. Measure the resistance between:

EOT sensor connector PI24, Battery
harness side
Pin 02 Negative terminal

- Is the resistance less than 10,000 Ohms?

->YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G531332t48.

G531332t48 : CHECK THE EOT SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between:

EOT sensor connector PI24, ECM connector PI300,
harness side harness side
Pin 01 Pin 10

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. This circuit includes harness splice, PIS49. CLEAR the DTC. TEST the system for normal operation.

->NO
INSTALL a new EOT sensor. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, refer to the warranty policy and procedures if an ECM is suspect.
