What is the P0335 fault code?
What’s the first thing you think of when you get into your car to drive to work each morning? What is the crankshaft’s position? It is not. However, the crankshaft plays an important role in the operation your vehicle’s engine. It converts linear energy to rotational energy. The crankshaft’s position is critical to the alignment and proper operation of the engine pistons. OBD-II-equipped vehicles have a crankshaft position sensor that transmits crankshaft position information (PCM/ECM/ECU).
The crankshaft position sensor, (CKP), is used to measure the engine’s rotational speed (RPM), and the precise position of its crankshaft. This sensor is required to start your vehicle’s engine. Fault code P0335 is generated when the vehicle’s host computer, also known as the powertrain controller module (ECM/PC/ECU/ECU), cannot detect the signal from the crankshaft positioning sensor. This is accompanied with a check engine lamp.
The CKP sensor tells the vehicle’s computers how fast the engine runs. This information is used to inform the engine control module (ECM) when to inject fuel. It also tells the ECM when to ignite the mixture of air and fuel.
The CKP sensor is used in conjunction with a crankshaft-mounted reluctor ring. The sensor is moved in front by the reluctor ring. The sensor sends an electrical signal to the ECM in order to know the crankshaft position. If the ECM doesn’t know the crankshaft position it will generate code C0335.

What is the P0335 Fault Code?
Sometimes it can be difficult to determine the source of the P0335 fault code. There are many options. The crankshaft position sensor may be responsible for the malfunction. The Powertrain Control Module is another possibility. This error code could be caused by a defective crank sensor, as well as other output signals. A damaged timing belt, or reluctor rings could also be responsible for this error code.
- – Open or close circuit in the wiring harness
- Poor electrical connections
- – Defective crankshaft position sensor
- – Signal plate damage
- – A damaged or defective timing belt or timing chain
- Broken or damaged reluctor rings
- – Defective ECM
What are the symptoms of P0335 Fault code?
The cause of the P0335 fault code can have different symptoms. With code P0335, some vehicles may not be able to work. Even if your vehicle does work, you may find it unusable because of problems like engine misfire, engine stalling, and high fuel consumption.
- Engine fault light on
- – Engine running hard, not running at all
- – Engine stalling, stalling
- Low engine power
- – High fuel consumption
The ECM adjusts fuel injection and ignition timing as your vehicle accelerates. An incorrect crankshaft position sensor can cause ECM problems, which could lead to vehicle acceleration issues.
Fuel injection will not function efficiently if it is not given the correct timing information. This will cause the engine to use more fuel than usual and will result in a lighter wallet.
An incorrect ignition timing can be caused by a faulty crankshaft position sensor. This could cause misfiring or other problems in one or more cylinders. Your vehicle may stall due to this.
The engine won’t start properly if it doesn’t have the correct amount of fuel.
At idle, you can feel the engine vibrate and stutter. This is caused by bad ignition timing.
How do I fix the P0335 fault code?
A scan tool is used by your mechanic to verify all codes in the ECM. The scan tool should examine all fault codes, current, past, and pending. After clearing the codes, a road test will take place to verify that symptoms are being observed. Next, the crankshaft position sensor (and wiring) will be visually inspected.
The system will continue to test the crankshaft position sensor readings as well as the RPM signal. It should verify that both cables are functioning properly. The ECM will then be tested using manufacturer-specific testing procedures.
P0335 is most commonly caused by the crankshaft position sensor. However, all components must be thoroughly checked including the timing belt and sensor ring.
- – Replacing your crankshaft sensor
- – Wiring harness repair and replacement
- ECM Replacement
- – Replacing signal plate
- – Replacing the timing chain or belt
What is the importance of the P0335 Fault Code
P0335 means that the engine is experiencing serious electrical or mechanical problems. You must immediately fix the problem to prevent further damage to the engine.
