Chevy S10 - GMC S15 and Sonoma Warning lights and trouble codes

    I would suspect ignition wires. EGR valve location will be found in the owner manual, shows a under the hood picture and legend.

    Has anyone every got a code 42 on a 4.3L S10/Sonoma? My truck trips the check engine light sometimes when I am idling, and the code is 42. Code 42 is supposed to be something related to electronic spark timing, but I dont know what to fix or replace. Any help?

    The ABS light on my 2002 2.2l came on. Is there anything I can check before I take it somewhere?

    One item you can check that won't cost anything. Crawl under it and check out the wires and associated plugs that go to the wheel sensors. Maybe you ran over some debris in the highway and knocked a wire loose. Sometimes stuff happens. I had that problem with my kid's car and fortunately all I had to do was replace the wheel sensor, which wasn't complicated at all. :shades:

    check engine light on 97 s10 2.2,,code reads "p1133 manufactur controlled fuel and air metering" have replaced 'Map Sensor controll' didnt help..any ideas where to try next ? thanks :confuse: :confuse:

    "DTC P1133 O2S Insufficient Switching Sensor 1" This is what I get for a 99 Sonoma 2.2. GM codes are pretty much standard. It refers to the oxygen sensor in the exhaust manifold. The code does not mean change it, it means check it out.

    If this helps I find that my brake lights come on when air is low in tires

    You need to find a better mechanic.
  • Get a video Camera, Set it up at the bottom of the canyon.
    Get back in the truck, and go flat out full throttle over the cliff.

  • I have a 2001 V6 S10. The service light soon light just turned on, so I went and got it checked. It had a couple of numbers come up, with one being 1860. Pretty much they the service guy told me it was either the ignition or the solenoid. THe next possible problem could be the valve body switch. I was wondering if anybody else experienced this and what the cost was?
  • Ok so this morning I was on my way to work NO PROBLEMS... stopped for gas(shut the truck off)... filled the tank... went to start the truck.. and thats when the problem started... check engine light... (flashing random pattern) and rough idle as well as running.. went to Advanced auto after work and had them read the computer P0300 code (Multi-Cylinder Misfire) so picked up plugs and wires... (Bosch Platinum 2s and Autolite Professional) and changed them all out (record time too, 2 hrs) anyways still have the problem... any help?
  • Sounds like a cap/rotor failure or fuel pressure issue. Remove the dist. cap and check for watermarks, wear, or carbon tracking. Replace them if you see a problem. also if your fuel filter has not been changed it would be a good idea, being significantly less than a fuel pump. Bosch and Autolite SUCK in GM ignition systems, so replace with ACDelco unless you like changing parts often. You really get whatyou pay for in ignition (and any other electrical) parts.

    Hope this helps, and its not a dirty injector or valvetrain issue
  • I'm trying to find out what a Code PO147 HO2S Heater Performance Bank 1 Sensor 3 code applies to. This is on a 99 Chevy S10. Do you know?
  • Can the OBD I computer in a 1995 S-10 be replaced with an OBD II computer?

    Most likely not, because the necessary sensors for OBD-II won't all be there.

    It usually means the gas cap is leaking, but it won't stop it from starting.
