ok. Far from being a tech but I do a lot of my own repairs. Here is my situation.
car wouldn't start in morning. Turns over, no start. With key on, ticking sound from engine, sound is the throttle plate (butterfly valve) trying to open and then closing, a couple of times a second, ticktickticktick. Pressing the accelerator pedal has no affect on throttle position.
i bought an actron cp9125 code scanner, but it won't read any codes, just keeps saying "no link". Scanner works on a '97 ford.
so i'm thinking maybe the throttle position actuator failed? The throttle bore was pretty dirty, I sprayed it with cleaner but no luck.
i understand that the actuator isn't serviceable, so the whole unit would need to be replaced.
it's hard to tell what warning lights might be on, on the dash, but the check engine and the service engine (wrench icon on the saturn) lights stay lit when the key is left on. I don't know if they would go out if the car was running.
i've searched a little but didn't see this problem.
any help is appreciated,
have the same problem?
