It has to do with the emissions system and stands for: P0402: EGR → Excessive Flow Diagnosis The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. The amount of gas … Read more

Saturn SW P0401: EGR – Insufficient Flow Diagnosis

P0401 is a common OBDII trouble code that’ll pop up in the Saturn SW. It has to do with the emissions system and stands for: The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the SW’s EGR system. … Read more

Saturn SW P0340: CPS – Circuit Malfunction

P0340 is a somewhat common and difficult trouble code to diagnose. The Saturn SW is no exception to this rule. That’s because it’s a generic powertrain code. Generic codes tell you that there is a problem, but they don’t really tell you what particular part of the system is throwing the code.     OBDII … Read more

Saturn SW P0300: Engine Misfire Detected

P0300 is one of the most common OBDII codes that occurs in the Saturn SW. It stands for: P0300 is certainly a cause for concern, and can be a threat to the drivability the Saturn SW. It will often be accompanied by codes P0301-P0308. These particular codes also indicate that there is a misfire detected, … Read more

Saturn SW P0113: IAT Sensor → High Input Problem

P0113 is an OBDII trouble code that occurs when the Saturn SW’s engine management computer detects that there is an issue with the Intake Air Temperature (IAT) Sensor, specifically that there is a High Input Problem with it. P0113: IAT Sensor – High Input Problem The IAT sensor is responsible for measuring the air temperature … Read more

Saturn SW P0011: OBDII Code Diagnosis

P0011 is a very common trouble code. It affects vehicles with variable valve timing (VVT). The list of VVT vehicles is growing, and the Saturn SW can have VVT, and is prone to developing this code. P0011 is a generic OBDII code. This means that it has the same definition for the Saturn SW as … Read more

Saturn SW P0139: O2 Sensor Slow Response (Bank 1 -Sensor 2)

P0139 is a common OBDII code that occurs in many vehicles, including the Saturn SW. The code is triggered when there is an issue with the response time from the oxygen (O2) sensor when switching voltage levels. The Oxygen sensors are responsible for helping the ECM meter oxygen levels in the exhaust, and helping to … Read more
