What is the P0195 Fault code? What does it all mean?
Engine oil temperature (EOT), is a sensor that is typically used on diesel-powered vehicles. This sensor is responsible for measuring the engine oil temperature and informing powertrain control module (PCM) about it. It is vital to monitor the oil temperature of your engine because it can overheat and cause loss of lubrication.
The EOT sensor can be described as a type negative temperature coefficient (NTC thermistor). The oil temperature is directly proportional to the sensor’s internal resistance. The voltage signal drops as the engine oil temperature increases. However, it will increase when the oil temperature falls. It receives a 5 volt reference from the PCM, and then sends a signal back to the PCM according the oil temperature. This information is used by the PCM to determine fuel quality, timing of injection, and glow plug operation. The PCM compares voltage signals from the EOT sensors with intake air temperature (IAT), engine coolant (ECT) sensors. If the PCM detects an issue with the voltage signal from EOT, a P0195 code will be issued.
The EOT sensor could not function properly if the engine cooling system is damaged. It is essential to address problems with the engine cooling systems first.
P0195 fault codes can be found on vehicles of all makes and models, including but not limited to Ford, Chevrolet, Fiat.
What is the P0195 Fault Code and Why Does It Happen?
Here are some reasons why P0195 should be set:
- – Defective engine oil temperature sensor
- – Damaged wires and connectors.
- – Engine cooling system malfunctions
- – Defective PCM (rarely)
What are the symptoms of the P0195 Fault code?
You may experience the following symptoms if your vehicle has a P0195 Code:
- – Illumination and control of the check engine light
- – Engine overheating
- – Set fault codes in relation to engine coolant temperature
How to Fix the P0195 Fault Code
The following repairs may be able to resolve the P0195 fault code:
- – Repairing an engine oil temperature sensor that is defective
- – Repairing broken wires, connectors and open or short circuits to an engine oil temperature sensor circuit
- – Repair of any cooling system problem
- – Repairing a damaged PCM (rarely).
How serious is the P0195 Fault code?
Moderate severity is the P0195 code. This code may be used in conjunction with coolant temperature codes. This could cause engine damage and overheating. It is a good idea that you address this code as soon possible.
