What problem codes are set? Most often, these symptoms are the result of a failed throttle position sensor (https://www.yourmechanic.com/services/throttle-position-sensor-replacement). Traditionally, cars will have a throttle cable but your Saturn has a "fly by wire" throttle system. If the engine management...

The first thing to check is to make sure the battery has proper voltage of at least 12.5 volts. Then make sure the battery cable ends are clean and tight. Make sure any corrosion is cleaned off them to give...

Hello, thank you for writing in. When it comes to a stalling issues, you want to turn your attention to the spark and power supply first. It is good you have partially ruled out the fuel supply as the problem....

Hello - the mass airflow (MAF) (https://www.yourmechanic.com/question/what-does-the-mass-airflow-sensor-do) sensor is the black plastic cylindrical tube with an electrical harness that goes into the air filter housing on your engine air intake system. I would check for problem codes first however, as...

Hi there. I completely understand about time constraints and your concern about a potential fire hazard. Many people continue to drive their vehicles even if there is oil on the exhaust components as they usually smolder and smoke. However, the...

Hello. These lights can mean that there is a serious issue going on or that there may be an electrical malfunction. I usually check and see if there is oil pressure and check to make sure that the charging system...

It sounds like you are describing the BCM (Body Control Module) (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-electronic-brake-control-module-ebcm). It usually has 3-4 connectors. Saturn vehicles are unique. Like many vehicles, there are not any other vehicles that I know of that you can use for parts....

The axle bore in the transaxle needs to be checked for debris, burying, or a damaged locking ring that could be preventing the axle from fully inserting into the transaxle axle bore. Also, replacement axles are generally refurbished from used...

Since I don't know what kind of chip you have or the specifics of how it was installed, I'm not sure how much advice I can provide. But first, I would start by double checking that everything is exactly how...

Hi there. There are a few different things that can go wrong and cause this. Most of the time, if it is intermittent it is due to a belt that is coming loose or a clog in the system. I...

Hello, since the fluid is full and you state the air conditioning is also failing, you should check the front of the engine and make sure that the drive belt is present. If the belt is present, I would say...

This may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear, making turns (which makes use of the power steering pressure switch) turning on...

Hi There, It sounds like you may have a faulty traction control module. As you know, the traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by...

The vehicle could have a clogged catalytic converter, the fuel filter and/or injectors could be plugged and there are other possibilities in the fuel, ignition, and air induction systems. It is also possible that your vehicle has entered "limp mode"...

This may be related to low transmission fluid, or potentially a faulty transmission speed sensor (https://www.yourmechanic.com/services/transmission-speed-sensor-replacement) or transmission control solenoid. Every time a gear change is required, the car's computer activates a transmission solenoid, which directs transmission fluid into the...

All of these problems are most likely not related to each other. The no start is the most serious and may be due to the fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement) or ignition module not working. You will need to have the vehicle...

A clogged catalytic converter can increase exhaust system pressure robbing the engine of power. Along with this overheating, excessive fuel consumption can also occur. The exhaust system pressure should be checked and compared to specification to ensure the catalytic converter...

Hi. It seems to me that your EGR valve and EVAP need to be replaced. The car is hard to start because the pressure in the system is not correct in order for the engine to run efficiently. I would...

A vehicle not moving when put into, drive can be caused by many things. The problem may be as simple as the need to add some transmission fluid to as serious as the need for a replacement transmission. As the...

The first two codes point to the bank 2 sensor 2 and could be a problem with the wiring to the sensor or the catalyst is broken up and clogged the exhaust. The last code P0402 is for the EGR...
