The P0195 fault code refers to a malfunction in the Engine Oil Temperature Sensor. This sensor plays a crucial role in measuring the temperature of the engine oil, which is vital for optimal engine performance and longevity. When this code is triggered, it indicates that the engine control module (ECM) has detected a problem with the sensor or its circuit.

What are the symptoms of the P0195 code?

Symptoms associated with P0195 can include:

• The check engine light illuminating on the dashboard.
• Incorrect oil temperature readings displayed on the gauge.
• Poor engine performance, leading to reduced fuel efficiency.
• Possible overheating issues if the sensor is providing inaccurate readings.

What causes the P0195 code?

Common causes of P0195 include:

• A faulty engine oil temperature sensor.
• Wiring issues such as frayed or damaged wires connecting the sensor to the ECM.
• Poor electrical connections or corrosion at the sensor's plug.
• An engine oil temperature that is outside the normal operating range.

How to fix P0195?

To address the P0195 code, the following steps can be taken:

• Check the engine oil temperature sensor for faults and replace it if necessary.
• Inspect the wiring and connections for any signs of damage or corrosion and repair or replace as needed.
• Clear the fault code from the ECM and perform a test drive to see if the code reappears.
• If the problem persists, further diagnostics may be required to check the ECM itself.
