Indiana Posted March 20, 2010 Report Share Posted March 20, 2010 If some sensors are not properly adjusted it won't work so that doesn't mean its bad it might just not be activated. Read the faq about adjusting your idle. Link to comment Share on other sites More sharing options...
mikec Posted March 21, 2010 Report Share Posted March 21, 2010 The ISC assembly is attached to the backside of the injection mixer assembly. Stand at the driver side fender... lean over the two fuel injectors. Just to the right of them you'll see a fairly flat metal bracket screwed to the injection mixer assembly. Just below this plate, pointing at the driver side fender, you'll see a black plastic/rubber cylinder: this is the ISC motor itself in a protective cover. It's just a small direct current motor. Look at the flat metal bracket again: see the cylinder shaped bump on it, about half an inch tall and maybe 3/8ths of an inch in diameter? Underneath that is the Motor Position Sensor (MPS) potentiometer. Now cross over to the passenger fender and look at this bracket assembly from that angle. You'll see where the throttle cable has a support bracket and then continues to the "throttle sector." Just to the side of this you'll see a silverish piece hanging from the ISC flat metal bracket; this silverish thing will end in a rubber bellows. That is the ISC gearbox assembly. The bellows end goes up/down when the ISC motor is driven by the engine computer (ECU) to control the idle RPMs. At the very tip of the rubber bellows is the famous idle/nose switch - you can't see it though without taking the ISC+MPS assembly off the car. mike c.
