We have a 2003 pontiac bonneville, and we are getting a P0336 code, we took the car in to george white car dealer here in Ames, Ia. To be fixed back in October this year. They say they fixed it but we still get the code as well as the original problem of the car not starting. We took it back to the dealer and they say they basically can't figure it out. Can you help here? The dealer also say they had to replace the fuel pump which they said was going bad as well. And we ask that a tune up be down as well which the bill indicated they did. Can you please help and if possible forward this info on to George White Pontiac/ GMC here in Ames Ia.

DTC P0336: CRANKSHAFT POSITION SENSOR CIRCUIT
NOTE:To locate components, see COMPONENT LOCATIONS. For circuit reference, see WIRING DIAGRAMS. For connector terminal identification, see CONNECTOR IDENTIFICATION. For intermittent conditions, see INTERMITTENT CONDITIONS under SELF DIAGNOSTIC SYSTEM. If testing requires component removal or replacement, see appropriate REMOVAL & INSTALLATION article.
Description
Crankshaft Position (CKP) sensor is connected directly to Ignition Control Module (ICM). CKP senor consists of the following circuits:
12-volt reference circuit.
Low reference circuit.
CKP sensor 1 signal circuit.
CKP sensor 2 signal circuit.
CKP sensor shares power supply and low reference circuits with camshaft position (CMP) sensor. If the PCM detects no 18X reference pulses in one engine cycle. DTC P0336 sets.
Conditions For Running DTC
Engine is running and 3X reference pulses are being received.
Conditions For Setting DTC No 18X reference pulses are received in one engine cycle, 720 degrees of crankshaft rotation.
Action Taken When DTC Sets
The control module illuminates the Malfunction Indicator Light (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records. Conditions For Clearing MIL/DTC
The control module turns off the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

Diagnostic Procedures: referred to the two figures and follow the instructions

If you're asking me that question? The car runs but as you drive it, it will die, wait a few minutes and starts back up again.

Dr Loot. Any luck?

Different car but same issue and same code P0336. 1997 Camaro starts fine and after driving maybe 10 miles the service engine light comes on and it dies soon after. If I wait a few minutes it will start back up again.

CRANKSHAFT POSITION SENSOR A malfunction in the crankshaft position sensor circuit will set a related diagnostic trouble code. For testing procedures, see the TESTS W/CODES - 5.7L article. To diagnose crankshaft position sensor, the following procedures can be used:If a scan tool is available, scan RPM parameter while cranking engine. If RPM is indicated, crankshaft position sensor is operating properly. If scan tool is not available, disconnect crankshaft position sensor harness connector. Set ohmmeter to 2-k/ohm position, and measure resistance across sensor terminals. Resistance should be 800-1200 ohms. On all engines, set voltmeter on the 2-volt AC scale. Crank engine and measure output voltage across sensor terminals. Voltmeter reading should be.8-1.4 volts. If resistance reading is not as specified or sensor does not produce the specified output voltage reading, repair faulty wiring or faulty crankshaft position sensor.

Thank you Dr Loot. I've been chasing this one down for months and the last couple weeks it was getting worse. I could only drive 10 to 15 miles before I'd have to pull over and let it cool or face stalling in what always seemed to be a busy intersection.

I replaced the crankshaft position sensor and that was the fix as I've drive the vehicle 200 miles since without problem.

Reading up it appears this is a common problem in the 1997 Camaro. The biggest pain on the Camaro was removing the balance wheel to get at the sensor but wasn't too big a deal even for this noob.
