The hard part is that the sprocket must be off the car to do the factory way which is why the timing cover must be off. The approved factory "snap in" way is to insert into the cam sprocket from the back until the ears pop out in the machined recess. You will notice it is shaped like a top hat with two ears sticking out. To repair, first get the GM "interrupter" (magnet) p/n - 25530386 grp 0.736 about $14 retail (2002). Might want to check this first to see if it is really your problem. Roughly circular and sticks out from the sprocket. Timing cover with sensor in place Timing cover with sensor removedĬam sensor is directly under water pump (removed on cover shown)įig. However if pressed for time and money there is a way to replace the interrupter through the cam sensor hole and you only need to remove one bolt to do it. (Note, if over 100k or the timing chain feels loose if turning the balancer or an 88 or earlier, it may be a good idea to replace the timing chain and any worn sprockets/tensioners anyway - always use an 89 or later tensioner - while off do a water pump also.) Take to dealer and the quote will be over $500 since the book says the timing cover must come off. goes out sometimes or comes on a few minutes later, it is probably not the interrupter (magnet) - they do not heal. Note: if the SES or Check Engine light does not come on when the engine starts and stays on as long as the engine is running e.g. Getting a constant "code 41" that will not clear and the cam sensor is good ? Odds are the cam magnet (interrupter) has removed itself from the cam sprocket. Do the same with the 2nd gen sensor.Thanks to Padgett for this information. :Unsnap the case apart and remove the circuit board from the case. :Then make a nice work station to do some soldering. undo the wires and remove the sensor from the car. :Then use a 1/4 socket and ratchet being careful not to crack the windshield undo 2 screws holding the sensor down. :You will need to remove the 1st gen sensor from your car to do this you will need to pop off the upper dash cover by prying on each end with a flat blade screw driver then sliding it towards you and off the dash. :You can get an 2nd gen sun load sensor from any junk yard prices will very depending on the yard i would guess about $5-$15. it does involve desoldering, and soldering on a circuit board, so if you are not comfortable with that you might want to have somebody tackle this. this way will only cost you the price of a second gen sensor from the junk yard providing you already have a soldering iron and solder. Chrysler has discontinued the part and even then it is $70. It is a common issue to have the automatic headlights come on in the middle of the day on just about every 1st gen with auto headlights.
