Trouble Code P0341

Hi all,

The "check engine" light came on this past rainy weekend, so I ran to
AutoZone and got the codes read for free. Code P0341 came up, which means
there's a fault in the camshaft position sensor. The problem is that this
car is a '99 SL1 with the SOHC motor and there's no such sensor (or so I was
told).

This code has come up before, so I changed the plugs and wires, and it went
away. But it's back again and I'm not sure what to do next. I noticed that
after I had changed the wires and plugs, the ignition could be heard through
the radio. So I tightened things down and the buzzing went away. But that
too is back. The car runs fine, but the "check engine" light is on and
there's interference on the radio.

Has anyone else had this problem, and how did you deal with it?

Thanks,

 

We have a 97 SL2 and this code has come up twice since we had the car. (4
years)
The Saturn mechanic says it means nothing. Just reset light and it should go
away for quite a while.
They could fix it by changing a part whose name escapes me but they don't
because it's a waste of customer's money.
(How's that for honest?!)
Found this out when car wouldn't start due to cracked temp sensor, which
incidently didn't bring up a code.

You're right, there is no cam position sensor. However, what these engines
use to determine cam position is called compression-sense ignition - by
comparing the firing voltages on the #1 and #4 plugs, it can tell which of
them is on compression and which is on exhaust, and therefore know which
cylinder is actually on the firing stroke. This code indicates that the cam
signal that the PCM received was incorrect or had too many pulses per
revolution. Engine misfire or voltage leakage can confuse the system. If you
have radio interference, then you've got high voltage leaking to ground
somewhere - if it's not a bad plug or plug wire, then quite likely you have
a bad ignition coil..

You might want to read the information at the above link. This may be
as simple as a wire routing problem.
