P0495 OBD-II: Fan Speed High

P0495 Severity

Urgent

Should you fix P0495 yourself?

Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.

Proper diagnosis will save you time and money on unnecessary repairs.

Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.

Schedule Diagnosis

What causes OBD-II fault code P0495?

The purpose of the electric cooling fan system is to provide extra cooling capacity to the conventional radiator cooling system on hot days, and/or when the A/C is on, an/or when the vehicle is being driven in stop and go traffic which causes insufficient Airflow over the radiator. When the engine control module (PCM) cannot control the cooling fan as desired, it will set code P0495.
