Good mechanic near Roseville

Hey guys, my check engine light just came on today in my 2005 Chevy Silverado 1500. I was just wondering if you knew of any honest mechanics in the area that have a diagnostic tool to tap into the trucks computer system to find the problem? Thanks in advance!

Airjer is a great honest technician ..... another option is trying one of the Car parts stores that read the codes for free. Then we can maybe help you here.

Thanks Pier. Do you or anyone else know of a specific car parts store that will read the codes for free? If its not allowed feel free to email me.

Autozone does for sure!

Ok so I brought the vehicle in to a suggested mechanic in st. paul. The codes that were read were:

P0053 HO2S Heater Resistance B1S1

P0054 HO2S Heater Resistance B1S2

P0059 HO2S Heater Resistance B2S1

P0060 HO2S Heater Resistance B2S2

The mechanic said that the heater circut fuses were ok, and that he suspects there is an issue with either the PCM, or the wiring. He said that it was not very likely that all four O2 sensors are out/bad. Any ideas here? I have no clue what to think, except expensive.

The fuse where good but was there power at the fuses. I believe those are powered up by the ignition switch and the ground side of the heater is controlled by the PCM. I'll have to take a look at power distribution diagrams to see if how exactly those circuits are powers up.

Thanks for chiming in air...i'm just learning about most of this stuff, so bear with me. You say you think the fuses are powered by the ignition switch, then could a non-factory remote start cause any problems?(this could be a really dumb question, but all questions are worth asking imo)

I'm no expert so I can't say if its related or not but YES remote starters can and do cause problems.

I have no experience installing remote starters but I have plenty of experience uninstalling them to solve many issues! I'm not saying it is the problem but installers go willy nilly with the scotch locks and you have no idea whats tapped into what.

I had a VW the other day with an aftermarket stereo. You couldn't communicate with the PCM if the radio was on!
