SOURCE: I have a 1999 Pontiac Grandam that is pulling code

P0300 is a generic misfire code, it doesn't specify a cylinder (eg. P0301 cylinder #1, P0304 cylinder #4). Therefore its not likely realted to one cylinder like a plug, coil or one fuel injector, likely something related to all cylinders, possibly a bad 02 sensor reading (most likely), a fuel pressure regulator, low fuel pressure or partially plugged fuel filter. Change the fuel filter cheapest and easiest, then look into 02 sensor.

Crank and cam sensor replaced . cars starts and run but still reads code 335 . cranksensor circuit malfunction. and idea whats the issue why this code is still coming up.?


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.

Trouble code p0335


Replace the crankshaft position sensor and you should be up and running like normal. Verify that there is no power or ground problem to the crankshaft sensor, the Yellow/Black wire should have battery voltage any time the key is on and the main relay is energized.Verify that the Brown/Yellow wire has a good ground. If all is good then replace.


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.

A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector

Failed crank sensor
Broken timing belt
Failed PCM

3.6 in a 2006 pontiac g6 is throwing code p0017 is this crank sensors or what is the most common fix


P0017 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)

The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0017 code will set.

Symptoms of a P0017 will or may include:
* Malfunction Indicator Lamp (MIL) illumination
* The engine may run but with reduced performance
* The engine may crank but not start
* The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
* The engine may start and run, but poorly

Causes may include:
* Timing chain stretched, or timing belt skipped a tooth due to wear
* Misalignment of timing belt/chain
* Tone ring on crankshaft slipped/broken
* Tone ring on camshaft slipped/broken
* Bad crank sensor
* Bad cam sensor
* Damaged wiring to crank/cam sensor
* Timing belt/chain tensioner damaged

Possible Solutions:
1. First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck.
2. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor.
3. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

Other crank sensor codes include P0016, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.

02' Nissan Altima, car jerking, turns off at light, but turns right back on. Engine light on, code from autozone P0335 crankshaft position sensor. P0725 Engine speed signal circuit. The start up, days it...


If it has a code for loosing the crankshaft position sensor signal, I would certainly start looking at that before venturing into the fuel system. Cam and Crank sensors are a common failure item for Nissans of that era. Nissan actually redesigned the sensor and i think they performed a recall on some vehicles. They are fairly inexpensive and easy to replace. I believe they run about $40 each. Because most people don't have access to a powerful scanner or a digital storage oscilloscope to verify the failure I recommend replacing the cam and crank sensors at the same time.

What do codes p0335 and p0341 mean on 1996 Cavalier?


when your engine went into that 5 second sputter,
your computer or "PCM" did not get a constant signal from the crank or cam sensors that the engine was running.
These two sensors tell the computer what RPM the engine is turning so it can adjust fuel and spark.
