ECUs

Continue

Various Vauxhall models can experience error code P0335. This error code refers to a problem with the crankshaft position sensor and is often read out in Opel engines equipped with the Delphi Delco Multec HSFI-2.x / HDRC ECU (usually the 1.6 liter engine with engine code Z16SE). This error code can lead to reduced performance and even engine failures, and is therefore important to diagnose quickly and carefully.

Which Vauxhall models does error code P0335 occur in?

This error code is often seen in the following Vauxhall models:

Vauxhall Astra G (1998 – 2004)
Vauxhall Combo C (2001 – 2011)
Vauxhall Corsa C (2000 – 2006)
Vauxhall Meriva A (2003 – 2010)
Vauxhall Vectra B (1995 – 2002)
Vauxhall Vectra C (2002 – 2008)
Vauxhall Zafira A (1999 – 2005)

Symptoms of error code P0335

When error code P0335 occurs, the following symptoms may be visible:

MIL on: The engine malfunction indicator light (MIL) lights up on the dashboard
Starting problems: The engine starts with difficulty or not at all
Loss of power: The engine may deliver less power while driving
Irregular idling: The engine runs irregularly stationary, which can lead to shocks or vibrations
Poor acceleration: The car responds slowly to the accelerator pedal and accelerates less quickly

Tip: This problem can be caused by a defective crankshaft position sensor. In the beginning, the error can occur intermittently. Common complaints are the lack of control of the coil, the injectors and the idle adjustment motor. Defects can also occur in the 5-volt circuit and on the accelerator pedal, the throttle valve and the fuel pump relay.

Possible causes

This error code can therefore be caused by a defective crankshaft position sensor that has become defective or damaged. There may also be several other causes for the fault, including:

Problems with the wiring or connectors: Poor connections or damaged cables can disrupt the signal from the sensor
Error in the engine control unit (ECU): A defective ECU can also be the cause of reading error code P0335

If the crankshaft position sensor and the wiring and connectors have been found to be in good order, in many cases replacing or overhauling the ECU is the solution to the faults mentioned.
