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.
What causes the OBD-II generic code ” p0691 “?
P0691 is an OBD-II generic code triggered when voltage varies by more than 10% of the vehicle manufacturer’s explicit reference voltage. What causes the P0691 code?
What does the p0325 code on the knock sensor mean?
Code P0325 sets when the PCM determines the knock sensor signal falls outside of a predetermined threshold for a certain amount of time. The ‘Bank 1’ portion of the code indicates that the issue pertains to the knock sensor on the side of the engine that houses the number one cylinder.
Why is my ECU fault code not disabled?
Sensor voltage is going to 0V as part of normal operation but low voltage fault detection is not disabled (Error Low). The voltage at the analog input pin has been below the Error Low voltage for longer than one second. Sensor may be faulty. Volt channel sensor disconnected. Error Low setting incorrect.
When to use the p0966 transmission solenoid code?
Code P0966 is set by the PCM when it detects that the pressure control solenoid “B” control circuit is experiencing a low voltage condition and therefore is not functioning properly. Example of transmission solenoids:
What causes the p0079 OBD-II trouble code?
P0079 indicates an issue that is found when the Engine Control Module (ECM) tries to control the Bank 1 exhaust valve solenoid and finds the system readings to be out of range. Specifically, this code is found when the ECM detects low system voltage. This code is similar to P0078 and P0080. What causes the P0079 code?
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.
What kind of trouble code is a p0174?
While the P0174 OBD-II trouble code is not manufacturer-specific and is considered a generic powertrain code, it can be more common in certain car makes than others. More specifically, a P0174 is most often reported on Chevy and Ford vehicles.
