DESPERATE HERE - P0335 Crankshaft sensor - no acceleration
 

Desperationly need help here. We have a 2001 S40 that we had the head off.

Put everything back together, timed by all accounts perfectly..all marks align, slack out of the belt etc.

The car ran fairly well (had a turbo problem too) then we started getting cam/crank sensor DTC errors. The car would intermittently start/run excellent then not...we would some times disconnect the crank sensor and the car would start/then not??

We did replace both cam and crank sensors several times each.

Currently the car WILL start on its own without pedel but WILL NOT accelerate/rev up even at idle...both with and without the turbo pressure tube connected to the throttle body.

BTW the cylinder pressures are good and we have put on several crank sensors ALL of which tested good??

Please, we need to get this car fixed; we need to sell it for living expenses

I assume you had the battery disconnected while carrying out this work? Clear all the trouble codes, disconnect the battery for several hours to reset the ECU, make sure all your sensors are secure and connect your negative battery lead again.

What turbo problem did it have?

We have done that already; we have a SnapOn Solus current ed. Codes clear, even went so far as running tests from the crank sensor all the way to the computer, disconnected/left overnight stuff, new flywheel, multiple cam/crank sensors.

The turbo impellers were bad as well as the gasket between oil/water; the car was blowing smoke.

We've had the car running but it that was intermittent then total. We've checked for various grounds and found nothing....absolutely stumpted here.

Hooked up our scanner to see if we see the crank/cam sensor readings...nothing specific there...we do see engine rpm which to us IS the crank sensor reading.

Since can't see actual cam/crank readings to see if they are out of range of each other causing this problem.

Did you ever solve the problem?
