Code 41 intermittent

parts costs for any car , on earth are not the same all over earth
not even close, .
unless in N,Korea or Cuba.
new, used , rebuilt
beside the mount error
all those error could be just 1.
even vacuum leak.
P0300 says all cylinders misfire so there other P030x error are pure redundant.
cam sensor is serious, in the real world that cam sensor error is very serious. and causes misfire, so misfire is expected

why add up cost when you've no clue what is bad.
OBD2 DTC are just the starting point of diagnosis
the PCM is not AI, not by a country mile ,even to the moon.

we cant watch you or the car ( in the secret act)

did you crank a dead engine so LONG, that battery went low and now all computers in the car are telling lies, and is common as nails now. this effect..
no symptoms told at all just a DTC dump.
no engine told at all and A4
4.2 L V8 40v DOHC >< complex this.
seems it is just 1,
posted ANON so no other way to know what engine is here.
nor there post full of symtoms not told here
and what happened the day this all started.
engine died? what?
starter cranking slow is not good,
step 1 on all cars , we keep the battery fully charged till the engine starts to run and stays running and battery volts are 13 to 15vdc,
a volt meter tool find that easy.
if below 13vdc the alternator is dead or its fuses.blown.


also we do not sell engine parts. here. just free advice ,just that.
no miles on the car told, over 90,000 miles
and the silly cam belt failed. making CAM sensor go dead?
the belted cams can not be ignored
the belts are changed out at 90k miles 140km

good luck , DTC codes are not AI, not at all

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.

Points worn? Did they still use points in '92? If so, replace points and condenser.

Sound like the cam sensor is loose and not seated properly or has something foreign on it.

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.

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

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.

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

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.
