Saab 9-4X P0335: Crankshaft Position Sensor “A” Circuit Malfunction

The Saab 9-4X utilizes a crankshaft position sensor in order to regulate the engine timing. This sensor uses a reluctor to gauge the position of the crank. When the 9-4X’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code.   P0335 Symptoms: Saab 9-4X … Read moreSaab 9-4X P0335: Crankshaft Position Sensor “A” Circuit Malfunction

Saab 9-4X P0138: Oxygen Sensor High Voltage (Bank 1 -Sensor 2)

  P0138 is a common OBDII code that occurs in many vehicles, including theSaab 9-4X. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more Voltage to the sensor is to high (wiring problem, think short) Bad O2 sensor itself There are also some less likely problems … Read moreSaab 9-4X P0138: Oxygen Sensor High Voltage (Bank 1 -Sensor 2)

Saab 9-4X P0133: Oxygen Sensor Slow Response (Bank 1 -Sensor 1)

  P0133 is a common OBDII code that occurs in many vehicles, including theSaab 9-4X. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The O2 sensor is responsible for helping the ECM meter oxygen levels in the exhaust in order to … Read moreSaab 9-4X P0133: Oxygen Sensor Slow Response (Bank 1 -Sensor 1)

Saab 9-4X P0132: Oxygen Sensor High Voltage (Bank 1 -Sensor 1)

    P0132 is a common OBDII code that occurs in many vehicles, including the Saab 9-4X. The code is triggered when: The voltage at the sensor remains above threshold for 20 seconds or more. The air fuel sensor stays in rich biased mode for too long. There are also some less likely problems that can … Read moreSaab 9-4X P0132: Oxygen Sensor High Voltage (Bank 1 -Sensor 1)

Saab 9-4X P0330: Knock Sensor ” Bank 2″ – Circuit Malfunction

P0330 is a powertrain OBDII trouble code that has the same meaning for the Saab 9-4X as it would any other vehicle. By definition, it means that the vehicles ECM/PCM isn’t getting the proper signal from the knock sensor. Clearing this code typically requires a new knock sensor. The second most common cause is a … Read moreSaab 9-4X P0330: Knock Sensor ” Bank 2″ – Circuit Malfunction

Saab 9-4X P0130: O2 Sensor Circuit Malfunction (Bank 1 -Sensor 1)

P0130 is a very common OBDII code that occurs in the Saab 9-4X. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. Saab 9-4X P0130 Symptoms Typically, the only symptom of P0130 is going to be the service engine soon light. In some cases, there can be other symptoms … Read moreSaab 9-4X P0130: O2 Sensor Circuit Malfunction (Bank 1 -Sensor 1)
