P0195 code definition

Engine Oil Temperature (EOT) sensor malfunction

What the P0195 code means

The intended purpose of this code is to indicate if there is a problem with one of the circuits that monitor the engine oil temperature. However, if there are cooling system problems, the diagnostics designed to confirm the proper operation of the EOT can interpret the results as a failure in the EOT system. For this reason, cooling system issues need to be addressed first.

What causes the P0195 code?

  • Faulty engine oil temperature sensor
  • Problems with the EOT circuit
  • Faulty powertrain control module (PCM)
  • Cooling system malfunctions

What are the symptoms of the P0195 code?

The only symptom is a Check Engine Light. The EOT system is there to detect other problems with the vehicle. If the circuits of the EOT system has problems, it will be unable to monitor the oil temperature.

How does a mechanic diagnose the P0195 code?

A scan tool should be used to watch the sensor data, but most often, a resistance check is performed on the sensor and is the final test performed before determining the source of the P0195 code.

Common mistakes when diagnosing the P0195 code

  • A technician chooses to replace the sensor without checking the wiring going to and from the EOT sensor.

  • Failing to check the reference voltage the PCM provides to the sensor.

  • Not identifying problems with the cooling system that can mimic the data that sets this code.

How serious is the P0195 code?

The P0195 code by itself is not serious. It will not leave an owner stranded on the side of the road. However, if the system is left unrepaired, it is possible that severe engine damage can occur if the EOT system is unable to detect the problems that it is suppose to monitor for.

What repairs can fix the P0195 code?

Additional comments for consideration regarding the P0195 code

A P0195 code is a generic code that all manufacturers can use and must always retain the same definition. The P0196 code is most commonly used for a wider variety of vehicles.

Each manufacturer utilizes a different diagnostic method for the testing of this system. Even then, it is often used in performance vehicles that are designed to be driven very hard. Driving in racing conditions pushes the vehicle to the limits of its engineering beyond what an everyday driver will experience. For this reason, an EOT system is not common on most vehicles.
