P0603 is a generic OBD2 trouble code. It indicates that your Ford Fusion’s keep alive memory has had an error. Keep alive memory is the data that your Fusion’s PCM (Powertrain Control Module) has learned about how your engine conditions. All of this sensor and driving input data is used to keep it operating efficiently. … Read more
P0522 is an OBD2 diagnostic code that is triggered when your Ford Fusion detects that the value being sent from the oil pressure sensor is below its normal operating ranged. It is typically caused by a bad oil pressure sensor or an issue with the oil system, and should be diagnosed and fixed right … Read more
The Ford Fusion utilizes a crankshaft position sensor (CKP) in order to regulate the engine timing. This sensor uses a reluctor to gauge the position of the crank. When the Fusion’s ECM determines that the signal coming from this sensor is out of range, it’ll throw the P0336 trouble code. P0336 is most commonly caused … Read more
P0308 is a fairly common trouble code with the Ford Fusion. It’s and OBD2 code and means that a misfire has been detected in the 8th cylinder in the firing order. You should only be seeing this code if you have an engine with at least 8 cylinders. So, it’s mostly a code for … Read more
P0307 is a fairly common trouble code with the Ford Fusion. It’s and OBD2 code and means that a misfire has been detected in the 7th cylinder in the firing order. You should only be seeing this code if you have an engine with at least 7 cylinders. So, it’s mostly a code for V8 … Read more
P0125 is a generic OBD-II code. If your Ford Fusion has registered it, means that the ECM/PCM is getting a signal from the engine coolant temperature sensor (ECT) that the engine is not warm enough to enter closed loop fuel control. P0125 is usually caused by a bad thermostat, low coolant, or a bad ECT … Read more
P0191 is a common OBD-II code. It indicates that the fuel rail pressure sensor is receiving a signal that is outside of its normal range. This is a generic code, which indicates that it has the same meaning for the Ford Fusion as it would any other vehicle. P0191 is typically caused … Read more
P0123 is a relatively common OBD-II code. It’s generic, which means it has the same meaning for the Ford Fusion as it would any other vehicle. It’s an OBDII code that references issues with the Throttle Position Sensor (TPS). It is relatively serious problem since it can leave your vehicle stranded or severely limited. The … Read more
P0332 is a powertrain related OBD-II trouble code. It has the same meaning for the Ford Fusion as it would any other vehicle. By definition, P0332 means that the vehicles ECM/PCM is getting a signal that is lower than the defined operational range from the knock sensor (Sensor 2 | Bank 2). Clearing this code … Read more
P0327 is a powertrain related OBD-II trouble code. It has the same meaning for the Ford Fusion as it would any other vehicle. By definition, P0327 means that the vehicles ECM/PCM is getting a signal that is lower than the defined operational range. Clearing this code typically requires a new knock sensor or correcting … Read more
