Chevy 2001 4.3L OBD code P0335, how to check for continuity

So did you do a google search for those codes to find out what they are. So you want someone else to do it for you.

Here's a link to your code P0335. http://www.obd-codes.com/p0335 The sensor you took out is good.

the sensor may be good its the circuit code which means can be a wiring /connection problem not just the sensor the following link is courtesy of obd-codes.comP0335 - Crankshaft Position Sensor A Circuit Malfunction OBD-II Trouble Code Technical Description Crankshaft Position Sensor A Circuit Malfunction What does that mean? 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. Symptoms NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start. Symptoms may include: Vehicle may not start (see above) Vehicle may run rough or misfire MIL illumination Causes 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 Possible Solutions Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal. If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs? If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay? If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault. This code is basically identical to P0385. This code P0335 refers to Crankshaft Posistion Sensor "A", whereas P0385 refers to Crankshaft Position Sensor "B". Other crank sensor codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.

is it a no crank or crank no start?
Possible causes for code P0335
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery

Question: where did you buy the new crank position sensor? I had the exact same problem with my 2004 Nissan Altima and bought new crank position sensor from one of the auto parts store. Put it in and same problem. I was baffled. Finally decided to get the crank position sensor directly from the dealer. Fixed the problem. This was my experience, not sure if your case will be the same.

unplug the MAF sensor and see if that helps.

I assume you have spark since it is backfiring. Will it start if you use a little carb spray in the throttle body?

If it does than you have a fuel issue. Check fuel pressure. You should see more than 35 psi roughly. If there is no fuel pressure than check for power to the pump (the larger of the two grey wires at the pump). If there is power than the fuel pump would be the first thing I suspected.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

there appears to be a problem with your crank position sensor and your oil pressure switch.

P0522 Engine Oil Pressure Sensor/Switch Circuit Low Voltage

http://www.jeepforum.com/forum/f28/p0522-engine-oil-pressure-sensor-switch-circuit-low-voltage-618006/

The crank position sensor or its connection is probably at fault. The engine needs the signal that the crank postion sensor provides to inject fuel and supply spark at the correct time.

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.

Symptoms:
NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start. Symptoms may include:
* Vehicle may not start (see above)
* Vehicle may run rough or misfire
* MIL illumination

Causes: 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

Possible Solutions:
1. Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
2. If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
3. If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
4. If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.
