The GMC Savana 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 Savana’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw the P0335 trouble code. P0335 Symptoms: GMC Savana … Read more
P0138 is a common OBDII code that occurs in many vehicles, including theGMC Savana. 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 more
P0133 is a common OBDII code that occurs in many vehicles, including theGMC Savana. 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 more
P0132 is a common OBDII code that occurs in many vehicles, including the GMC Savana. 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 more
The P0131 code is an OBD-II diagnostic trouble code that indicates low voltage in the GMC Savana’s Oxygen (O2) sensor circuit for Bank 1, Sensor 1 (B1S1). This sensor plays a crucial role in maintaining optimal engine performance by detecting the air-fuel ratio in the exhaust, then sending this data to the Savana’s engine control … Read more
P0330 is a powertrain OBDII trouble code that has the same meaning for the GMC Savana 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 … Read more
P0130 is a very common OBDII code that occurs in the GMC Savana. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. GMC Savana 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 more
P0150 is a very common OBDII code that occurs in the GMC Savana. It is typically caused when the Oxygen Sensor voltage is not within normal operating conditions. GMC Savana P0150 Symptoms Typically, the only symptom of P0150 is going to be the service engine soon light. In some cases, there can be other symptoms … Read more
P0161 is a very common OBDII code that occurs in the GMC Savana. It is typically caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 2 sensor 2. Replacing the Oxygen sensor will fix the problem a majority of the time. Some of the other causes of P0161 … Read more
P0155 is a very common OBDII code that occurs in the GMC Savana. It is caused by a failure in one of the oxygen sensors heated elements, specifically bank 2 sensor 1. The purpose of the heated element in the oxygen sensor is to quickly bring your O2 sensor up to normal operating temperature after … Read more
