P0336 code

Recommended Posts

Just wanted to verify before I started changing out parts.

2000 Base Boxster, 2.7 L Engine with 5 Speed Manual Trans., LH Drive

Car was running fine with no problems. Stopped at the cleaners and when I went to leave, engine would crank fine but no ignition. Towed it home. CEL had come on. Checked with Durametric and got the following code:

P0336 - Porsche Fault Code 110 - Engine Speed Sensor Open Circuit.

So, need to change out the Crankshaft Position Sensor. Correct?

(Just as an aside, I just finished changing out the CPS on my son's jeep this morning as it had failed. What are the chances of that, eh?!

It only took 2-3 minutes on his Jeep - didn't even need a lift since he runs on 32" tires. Suspect the Boxster will take a little longer.)

Check these first - but yes, likely a new CPS.

– Corrosion in connector– Open circuit or short circuit in wiring harness– Rpm/crankshaft position sensor faulty– DME control module faulty


1. Connect ohmmeter connector part to rpm/crankshaft position sensor, pins 1 and 2.Display at 20 °C: 0.8 – 1.0 k Ohms

2. Connect ohmmeter connector part to rpm/crankshaft position sensor, pins 1 and 3.Display: infinite ohms

If either test one or test 2 fail then it is definitely the CPS.

Last bad one I saw would work once it cooled down - but then drive a couple miles and things get hot it would open up again and shut off the fuel pump.
