What is P0335?
The P0335 diagnostic trouble code (DTC) indicates a malfunction in the crankshaft position sensor A circuit. This sensor plays a critical role in the engine's operation by providing the Engine Control Unit (ECU) with information about the position and speed of the crankshaft. If the ECU detects a problem in the circuit, it triggers the P0335 code. In practical terms, this can lead to a range of issues, such as poor engine performance, misfires, or even the engine not starting at all. This code is particularly prevalent in vehicles like the 2010-2015 Honda Accord and the 2007-2015 Toyota Camry, where the crankshaft position sensor can be vulnerable to wear and tear due to engine vibrations and heat. Ignoring this code can result in more severe engine damage over time, as the ECU may not be able to accurately synchronize the ignition and fuel injection processes, leading to inefficient combustion and increased emissions. Therefore, timely diagnosis and repair are essential to maintain your vehicle's performance and longevity.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0335 is present:
- Check engine light stays on constantly, indicating a persistent issue that may require immediate attention.
- Engine hesitates during acceleration, which can lead to a frustrating driving experience and safety concerns.
- Fuel economy decreased by 10-15%, suggesting that the engine is not operating efficiently, which can lead to increased fuel expenses.
- Engine may stall unexpectedly, posing a significant safety risk while driving.
- Rough idling or misfires can occur, causing the engine to shake or vibrate abnormally while at a stop.
Possible Causes
Most common causes of P0335 (ordered by frequency):
- The most common cause is a faulty crankshaft position sensor, which accounts for approximately 60% of P0335 cases. These sensors can fail due to heat exposure and vibration.
- Another frequent cause is damaged wiring or connectors within the crankshaft position sensor circuit, leading to intermittent or complete loss of signal to the ECU.
- Improper installation of a new crankshaft position sensor can lead to issues, so it’s essential to follow manufacturer guidelines during installation.
- Less commonly, a failing ECU may lead to code P0335, which is a serious concern as it requires replacement or reprogramming.
- A malfunctioning timing belt or chain can also cause this code to appear, as it may result in incorrect crankshaft positioning.
