I have changed both ckp and cmp sensors. I have ohm the wires from the pcm to the ckp and the cmp all fine, checked the 5v ref. to both also check the signal and ground it all turned out good. Where do I go from here do you think the pcm is bad?

Code p0335 refers to crankshaft position (CKP) sensor --circuit malfunction====causes ---wiring---ckp sensor ---ecm
you have checked the wires from ecm connection to sensor connection and eliminated the wires and connections so that only leaves a problem ECM
try substituting the ECM with a known good unit and see it the code is eliminated

What can cause a p0335 code to appear on my 2003 honda odyssey


code p 0335 refers to crankshaft position (CKP) sensor---circuit malfunction=== causes --wiring--CKP sensor ---ECM
at this point because you were in the area doing repairs to the power steering pump , it is possible that you have disconnected the wires to the CKP
check that or replace the CKP

Tying to find crank sensor for 2002 Cadillac Seville std 4.6 liter


This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.
tying-find-crank-sensor-2002-cadillac-3hcuyyaerdphtgzyedxwn2k0-1-0.jpg
The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

Replaced camshaft and crankshaft position sensors in my 2005 altima also the o2 seneor car still will not run. error code 335 What else could be the problem?


DTC P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using Fixya, and have a nice day.

Jose.

What are error codes P0372, and P0335


Hi, these codes relate to the crankshaft position sensor. Recommend you check the sensor to make sure it is tight and the connector is fully on. If it looks in order, consider replacing the sensor. If you reply with your model and year, I will see if I can provide additional information.

P0335 Crankshaft position (CKP) sensor - circuit malfunction
Possible causes: Wiring, CKP sensor, ECM

P0372 Timing reference, high resolution signal A - too few pulses
Possible causes: Wiring, CKP/RPM/CMP sensor, ECM
