#97 of 137 Isuzu Rodeo Check Engine Light
Apr 14, 2010 (9:42 am)
Help! I'm at my wits end. I can't get my Rodeo inspected because the check engine light will not go out. I've taken it to two car repair places and all they can tell me is that the computer won't let them override the light. It runs fine and I think the light is just a glitch in the car but I've already got two tickets for expired inspection and I don't know what to do. Can anyone offer me some suggestions?
I tried the gas cap thing. No luck.

Experienced the same problem twice. Onboard analyzer points to loose gas cap - First, the original cap has the rubber seal twisted. Second, the cap was not seated properly. Check rubber seal often and rotate cap three times when you place it back.

Since posting this question, I checed my gas cap and it states on the cap to turn until 3 clicks. Once I did this, no more check engine light until I forgot one day to turn cap three clicks.

I was having all sorts of reduced power, acceleration and stall problems. My mechanic said the wire harness on my 2001 Rodeo V6 with 99,500 miles whcih i just bought was falling apart and had been repired many times. So i bouhgt the new one and when my mechanic gave me the car he said was a hesitating at lower speeds and he checked the code which was a 300 which he said didn't have a diagnostic explanation. So he told me to put in a can of injector cleanrer. I told him i heard that the grounds need to be checked. He cleaned the 4 grounds on top of the engine and most of the hesitation is gone but now the CEL light is on. When i accelerate the CEL blinks but goes back on when the foot is off the acelerator. It idles fine just those little jumps at low speeds and the light is on. Are there more than just the four grounds to be cleaned? He also told me that he replaced the 2 front Oxygen sensors with Bosch sensors could this be the problem

We have the same problem. so I bought a OBDll code reader $30,and with this tool you plug it in under the dash below the steering column . This will read all error codes and tell you what it may be,but you can also erase the error code which in turn will shut off the check engine light for a day or so,enough time too get it inspected. Hope this helps. WE do this every time inspection comes due,our error code is for the EGR valve which would cost me around $200 to fix.

I just brought a 2000 Isuzu Rodeo and my 30 days are almost up and I need to get this thing registers but the check engine light is still on. I keep getting a EGR/ air flow reading, I have replace the fuel pump, and I have brought a new EGR valve. The check engine light just went off briefly yesterday, but it was late and by the time I got in there to drive again it was back on. I took it to AutoZone and the reading was still the same thing the EGR - air flow. I don't know what to try next, I keep buying the fuel injection cleaner, because everyone keep saying that I need to drive it cause it has a build up. It does have very high miles. I need a quick fix so I can pass the emissions test. HELP!
#106 of 137 Check Engine light just came on

I have a 1997 Isuzu Rodeo, it has been a great car. The check engine light just popped on and I don't want to take it into the auto shop just for them to tell me a bunch of stuff is wrong. Car still runs great, the light popped on yesterday. Any ideas on what it could be? I have about a 600 mile round trip coming up pretty soon...want to find out before i go on it.
