Engine check light came on again.

Hi everyone.

I'm getting sick and tired with this stupid engine check light again. Before I had P0137: oxygen sensor circuit, low voltage (post-converter sensor, left bank) and P0108: manifold absolute pressure sensor circuit, high input. I replace the pressure sensor, and a new o2 sim. On Monday when I was driving to my serrada scrima class. I look down to check my speed and bam the stupid engine check light again ##$$%^$#&%$&. So I stop by AutoZone and they ran a code for me. It said P0153 O2 sensor slow response. I just bout a new o2 sim and installed it on Friday. I check all the wire but everything look fine. My question is should I replace the o2 sim with a new one or a aftermarkt o2 sensor?

Thanks.

Re: Engine check light came on again.

its for your passenger side manifold sensor. visually inspect the wires and replace the sensor. grab a Haynes manual if you like to really go about diagnosing it.
