How do I fix code P0691?
Carefully inspect the engine cooling fan and its voltage and grounding. If there are any issues in the cooling fan relay and circuit, then it should be repaired properly. Inspect the engine temperature readings as it should lie between the manufacturer’s parameters. Replace the engine coolant temperature sensor.
What does code P0691 mean?
P0691 code definition The P0691 code appears when the powertrain control module (PCM) has detected an inappropriate level of voltage in the electric cooling fan’s control circuit. The level can be too high or too low.
What can cause a P0480 code?
The movement of the vehicle while driving forces air through the radiator and A/C condenser (it needs cooling too), but when the vehicle is sitting still, a fan or fans must move the air. Issues with the cooling fan, cooling fan relay, or fan circuit can cause code P0480.
What is a cooling fan control circuit?
Diagnostic Trouble Code (DTC) P0480 stands for “Fan 1 Control Circuit.” The engine cooling fan system is controlled and monitored by your vehicle’s computer and various sensors. The PCM detects the temperature increase through the coolant temperature sensor.
What does the OBDII code p0691 mean?
Engine Light ON (or Service Engine Soon Warning Light) Radiator fan inoperative The Engine Control Module ( ECM) monitors the Cooling Fan 1 Control Circuit. The ECM sets the OBDII code when the Cooling Fan 1 Control Circuit is not to the factory specifications. Need more information on how to fix the P0691 code?
How is the p0691 fan 1 control circuit low?
There are primary fans and some secondary fans, and the mechanic has to run a full test before simply replacing the primary fan motor. How serious is the P0691 code? The P0691 code does not prevent the car from running, but some vehicles can overheat at idle when this problem persists.
When to set the DTC for p0691?
DTC P0691 is set when the PCM senses the voltage low when the cooling fan 1 is off. Symptoms of a P0691 code may include: The possibility of the engine overheating due to non-operational cooling fans is very probable so caution should be used if driving the vehicle when the conditions to set this DTC are present.
How much does it cost to repair a p0691 circuit?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P0691 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
