Question about 2000 Saturn SL
HELLO TRYING TO GET MY SATURN INSPECTED AND IT HAS A HARD CODE MAKING THE ENGINE LIGHT TO COME ON IN NYS THIS FAILS THE INSPECTION FOR EMMISSIONS WHAT CAN I CHANGE OR FIX THANK YOU
To BIGHWEELS197, take your car to AutoZone and have them scan the computer - they'll do it for free, whereas the dealer will charge an hour's labor. Post the codes here and we can determine the problem.
To wjcomet, here are your code definitions:
P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1) - this means that the primary O2 sensor on the bank of cylinders with cylinder number 1 in it is not heating up quickly enough. The heating element is eventually getting it to temperature (it has to be heated up to work) but it's getting to be too long to heat up, which can fail you for cold-start emissions. You'll have to replace this sensor eventually.
P0341 Camshaft Position Sensor “A” Circuit Range/Performance (Bank 1 or Single Sensor)
This indicates a problem with your cam angle sensor. It could be that the sensor's pickup is not working right anymore (this does happen) but it could also be because your O2 sensor isn't getting to temperature soon enough and excess emissions are being detected, the car's computer may think that the cam position is off. If the cam isn't timed right, excess emissions can happen, so the computer may believe that's what is happening. I wouldn't be surprised however if the O2 sensor that's going bad is causing this code as well.
P0404 Exhaust Gas Recirculation Control Circuit Range/Performance
Indicates a failure of the EGR valve. Again, there's a chance that the failing O2 sensor can trigger this.
P1404 is a manufacturer-specific auxiliary emissions control failure code. I don't have access to that code's definition for your car, but again it's likely to be a result of the O2 sensor fault that you're having, since it's emissions-related and the O2 sensors are the main controllers of emissions on a car.
My advice would be to change that O2 sensor, have the codes reset, and see which ones, if any, return. If none come back, you likely had only the O2 problem and that fault caused the other codes as well. If one or more of the codes returns, we'll have to troubleshoot those individually.
