I mean P0135 and if so were r they located and aftergetting fix will thecheck engine light go out
The code P0135 is a fault code for the o2 sensor before the catalytic converter.Replace the o2 sensor and then reset the computer and it should be fine afterwards.The check engine light should stay off then.
SOURCE: 2001 Olds Alero oxygen sensor bank 1 P0135
p0135 indicates bank 1 sensor 1 which is before the cat.
SOURCE: Engine light came on after I went over a speed
the sensor is on you exgsaust pipe under the truck. if you slide under the truck behind the front tire. look at the pipe. you will see a sensor on the pipe with some wires coming out.
SOURCE: I took my car to
those are both codes for the bank 1 sensor 1 O2 heater circuit. If you have a voltmeter and now how to use it I can walk you through some steps on how to check.
This O2 (on the 2.2 liter) is located on the drivers side of the exhaust manifold about where it connects to the exhaust pipe. This is not an easy O2 to replace and does require a special O2 sensor tool to remove and install a new one.
I wouldn't have any problem replacing the O2 as a first step in resolving this issue. I would check the fuses to make sure they are good first!
