its probably a wheel speed sensor or " " harness. if you replace your hub assembly it will take care of the problem. a new hub will run you between $100-$130. its an easy fix if you have a little mechanical knowledge. i dont know what labor would cost but if you know how to change your brakes you can figur it out.

Check for carbon tracking on plug and wire. Looks like a pencil mark. Replace both at the same time

cam sensor is only half of the cam circuit, the other half of the cam circuit is the magnet on the timing chain. the cam sensor reads from the magnet every time the engine completes a revolution,
what happens is the magnet on the chain will break into smaller piece which makes the sensor harder to read every time the engine make a complete revolution.
most likely you'll need to replace the timing chain to fix this.

Not an intrigue, sorry. run over anything lately? A pinched cooler line could cause this. Or maybe just an old, gummy transmission.

Check for a vacuum leak. 13 is oxygen? If so, it may be a leak. If not, it may be a bad plug. Have you changed anything? Tried to get a code?

What is trouble code 41 for 1988 olds 98???


It indicates a problem with the cam sensor. The problem could be a defective cam sensor or it could also be the magnet attached to the cam gear that the sensor detects. They have a history of falling off after many heating and cooling cycles. If the magnet (about the size of a dime) is missing, replacing the cam sensor won't help. The magnet will need to be replaced.

My 1991 Buick Park Avenue is throwing off code 41. I have replaced the cam sensor, knock sensor, and the ignition control modual under the coils pack. The car will work fine then the check engine light...


there is a little magnet inset in the camshaft gear that the camshaft sensor gets its signal from. this magnet, over a period of time, gets loose and falls out. the reason for the smooth running when the light is on is the ECM sets the ignition timing to base due to the loss of camshaft signal. to replace the magnet you will have to remove the timing cover to access the cam gear.

I have a 2003 Dodge Stratus 2.4L DOHC Engine. The


it went from a hard cam sensor failure to an intermittent theres no magnet just a raised portion on cam.i think you got a loose terminal in the connector or a wire shorting or partly open from the sensor to the pcm

1988 olds 98 sets engine codes 41,48, and 63. stalls intermittently, but starts up again and runs fine. Before it stalls, the speedomoter blips down to half the speed and goes back up to the correct speed.


41- cam sensor reading, 48- EGR , 63- cruise control, 20 mph or more over set speed ( sounds like the speedo prob ).My thinking is the cam sensor code and egr code contribute to your stalling problem . Clear computer codes by pushing OFF and HI on A/C panel ( if its an AUTOMATIC CLIMATE CONTROL )ater reading codes. Then drive till problem occurs again and the light comes on. Now, read the CURRENT CODES, and that might eliminate one the codes / causes. Hope this helps

a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.

My " service engine soon" light kicked on.


The cam sensor is a magnetic ring that senses what position of 360* it is at. It is responsible for telling the computer when and which fuel injector to fire. Being that the care is running fine this indicates that there is an intermittent fault at work. I would have it checked by a tech as I am one. I would also tell the tech that it is an intermittent problem, basically he will figure it out if you describe it the way you told me. It is going to come down to an engine diag. The price veries from shop to shop about 150 to 200,
this price does not include parts or labor.
