Mitsubishi Diamante P0335: Crankshaft Position Sensor “A” Circuit Malfunction

The Mitsubishi Diamante 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 Diamante’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code.   P0335 Symptoms: Mitsubishi Diamante … Read moreMitsubishi Diamante P0335: Crankshaft Position Sensor “A” Circuit Malfunction

Mitsubishi Diamante P0133: Oxygen Sensor Slow Response (Bank 1 -Sensor 1)

  P0133 is a common OBDII code that occurs in many vehicles, including theMitsubishi Diamante. 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 moreMitsubishi Diamante P0133: Oxygen Sensor Slow Response (Bank 1 -Sensor 1)

Mitsubishi Diamante P0325: Knock Sensor “1” – Circuit Malfunction

P0325 is a powertrain OBDII trouble code that has the same meaning for the Mitsubishi Diamante as it would any other vehicle. By definition, it means that the vehicles ECM/PCM isn’t getting the proper signal to or from the knock sensor. Clearing this code typically requires a new knock sensor or correcting a short or … Read moreMitsubishi Diamante P0325: Knock Sensor “1” – Circuit Malfunction

Mitsubishi Diamante: Flashing Check Engine Light Diagnosis

A flashing check engine light is your Mitsubishi Diamante’s way of saying “I have a serious problem, don’t ignore me”. Most of the time, that serious problem is a misfire.  This flashing light should not be ignored.  When your engine is misfiring, it is dumping raw fuel into the exhaust.  This raw fuel can detonate, … Read moreMitsubishi Diamante: Flashing Check Engine Light Diagnosis

Mitsubishi Diamante P0132: Oxygen Sensor High Voltage (Bank 1 -Sensor 1)

  P0132 is a common OBDII code that occurs in many vehicles, including the Mitsubishi Diamante. 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 cause … Read moreMitsubishi Diamante P0132: Oxygen Sensor High Voltage (Bank 1 -Sensor 1)

Mitsubishi Diamante P0122: TPS “A” Circuit Low Input
