Question about 2000 Saturn SL
Having problems passing the emissions test. Keep getting a reject reading. I took the test 4 times and I keep getting a reading that the oxygen sensor, the egr system, the evaporative system and the catalyst
Just maybe your O2 sensors are not operating properly. They may be requiring your engine to heat them up to get upper temperature readings but not lower. You can easily diagnose these and all other sensors and problems by purchasing a Hains manual at your local Auto Zone or Advance auto store which will greatly aide you in diagnosing all your auto needs. And the fault symptom index at the beginning of the book will ease your troubles with professional one on one advice with step by step instructions. Its like having your own ASE certified mechanic at your finger tips. Good luck.

take you car over to auto zone or one of the part stores that do the free computer test. They will do it for free and sell the part to you for way less money.

The evap system allows for gas vapors to be recirculated through the system and burned by the engine,rather than vented into the atmosphere.
It means that the Gas cap is bad,the evap canister is clogged,you have a bad hose,or a sensor is bad.Replace the gas cap first,This is a common problem.
