P0402 is an OBDII trouble code that’ll pop up in the Saturn SL. 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
P0401 is a very common OBDII trouble code that’ll pop up in the Saturn SL. It has to do with the emissions system and stands for Exhaust Gas Recirculation (EGR)→ Insufficient Flow. The EGR system in your car is responsible for recirculating exhaust gasses in order to lower the vehicle’s emissions output. There are three … Read more
One of the more common engine management trouble codes that can occur in the Saturn SL is P0340. It’s a generic code, which means it has the same definition for every car or truck made after 1996. P0340 is related to the camshaft position sensor and points to an issue with the wiring harness connected … Read more
P0300 is a generic OBDII code that can occur with the Saturn SL. This code indicates that your car’s engine is misfiring and can be a drivability threat. P0300 is often accompanied by cylinder-specific misfire codes (P030X, where the X indicates the cylinder number that is misfiring). If you have P0300 and a cylinder-specific misfire, … Read more
P0113 is an OBDII trouble code that occurs when the Saturn SL’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
P0011 is a common (and serious) OBD II diagnostic trouble code that can occur in the Saturn SL. It indicates an issue with your car’s Variable Valve Timing (VVT) system. The first thing you should do when you have this code is check your SL’s oil. If the oil level is too low, the camshaft … Read more
P0139 is a common OBDII code that occurs in many vehicles, including the Saturn SL. 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
P0010 is a relatively common trouble code. It affects vehicles with variable valve timing (VVT). The list of VVT vehicles is growing, and the Saturn SL can have VVT and is prone to developing this code. P0010 is often by low or sludgy oil. Check your SL’s oil as soon as possible. P0010 is a … Read more
P0140 is a generic OBDII trouble code. It has the same meaning for any vehicle with OBDII, including the Saturn SL. It means that the PCM/ECM is not detecting any activity from the sensor. It doesn’t mean that the O2 sensor isn’t getting power, but that the voltage isn’t changing, which is the “no activity”. … Read more
