I had one go bad on my old 5ktq, and have replaced the same reference
sensor on two other 5ktq's. Every one of them reported the error
correctly through the ECU fault test. I haven't followed this thread,
but have the codes been pulled from the ecu?

The symptoms that the sensors were failing was exactly the same on all 3
crs. they would start cold and run fine, then when shut off and tried to
start again while hot they would not. My theory on this is that the
mangetic efficiency dropped to a point that it was not recieveing a
strong enough signal off of the timing pin when the flywheel was turning
so slowly (under starting conditions) to tell the ECU to start looking
at the dizzy window.

All of the cars sensors were replaced with tested used ones, and are
still running/starting strong years down the road now....

Just FYI out of memory the error code for this sensor is 2132 or
something like that, it's listed on the FAQ in my site.....

Later!
