I've got a 97 Chrysler COncorde with 90K miles.
The check engine light is on and when I check the codes
I see
code 54- No camshaft position sensor signal to distributor. Problem
with the
distributor sync circuit.
code 43- Peak primary circuit current not achieved with the max dwell
time.

I checked the cam sensor and the lower voltage does not look right. it
is supposed to read .3 volts and I am reading .047 volts. The higher
voltage
of 5 volts looks correct. I'm going to change the cam sensor and that
should
remedy code 54. I'm also due for spark plugs and I'm going to put new
ignition wires in. Any thoughts what is causing the code 43? Could it
be related to the cam sensor? Got to get this through inspection next
month.

My wife's 93 LH car has periodically thrown a seemingly random code 43.
Maybe 3-4 times in the life of the car so far. It usually clears itself.
It seems to happen more often when the plugs and wires are getting old,
so my guess is that a bad plug or wire is causing a misfire and altering
the primary current profile from normal, tripping the code.

If it's the 3.5L, look for possible leaking intake manifold gasket.
Also check for corrosion on the PCM connecotrs and ground straps for the
PCM.

Replaced at 200,000 miles "just because." Turns out it was weeping
coolant at the back corner, but wasn't leaking into the intake passages
at all yet. Dont' really see how that would cause a code 43, though.

Ground strap checking should be a sorta routine maintenance on that car.
But the rare code 43 seems more related to plug wire condition than
anything else.
