I have a 07 Chrysler Sebring 2.4 sedan I went to autozone to check my car out for any codes when they scan my car i had three code telling me my 02 sensor are bad sensor 1 bank 1 up stream so I change both sensor they it told me my cat was bad so I change thAt as well also change camshaft sensor and the check engine light is still on what u think it could be

 

are the codes the same? what are the codes? and Not all the time just because a code pops up does not mean that its for that item. If it were all that simple I would be out of a job and an Associate degree and 18 years of training is worthless.

 

The codes are p141 heated sensor 1 bank 1

 

I went to auto zone again to scan it again and the code that came up p0038 and p0032 02 sensor when I change it three times already

 

Codes for lambda sensors rarely mean the sensor is faulty. It's usually an air leak or a problem further up the air system like an air flow meter or something along those lines

 

U used BOSH o2 sensor huh?

 

Yea i use bosh 02 sensor

 

What u think I should do to fix it tired of seeing the check engine light on

 

Bosh are not compatible with chrysler U will need an NTK or DENSO o2 sensor take them back.

 

Denso should fix the problem should I change both sensors or just the upstream
