Question about 1998 Saturn SC

1 Answer

PO133 02 Sensor

So I JUST bought this car yesterday and half way home the Check Engine light came on, upon scanning it was an 02 sensor code (Bank 1, Sensor 1).
I had the dealer purchase the sensor for the car and when I installed it it didn't fix the problem... It is sluggish to start but runs just fine... What could be wrong with it??

CODE PO161 IS REGARDING OXYGEN SENSOR BANK2 SENSOR2 WHICH IT IS LOCATED IN THE BOTTOM RIGHT SIDE OF THE CAT ON THE OUTPUT OF THE CAT.REGARDING CODE P1135 IS FOR AIR FUEL RATIO OXYGEN SENSOR MALFUNCTION BANK1 SENSOR 1. MY OPINION CHANGE THE SENSOR BANK 2 AND RESET THE FAULT USING A SCANNER AND DRIVE IT. I BELIEVE WILL SOLVE THE PROBLEM.

1996 Toyota 4runner 3.4L error code p0133


SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

2005 gallant with O2 sensor engine light is one...how do I fix it?


have the engine light code scanned, and it'll tell you if it's bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1, bank 2 sensor 4.

Bank 1 is on the same side as Cylinder 1
Bank 2 is on the opposite side of Cylinder 1

Sensor 1 is located before the catalytic converter.
Sensor 2 is located after the catalytic converter
