What is fault code number?

Diagnostic Trouble Codes, also known as engine fault codes, are five-digit codes that identify a particular problem in the car. These codes are displayed on the scanning tool when it’s connected to the OBD system. The five-digit DTC includes one letter usually followed by four numbers (e.g. P1234).

What is wastegate solenoid?

The turbocharger wastegate solenoid is pulse width modulated by the PCM to allow fine-tuning of the turbo boost to more exactly meet engine operating conditions. The solenoid is a common failure point – symptoms of failure will include incorrect boost level and frequently code P0243 (WASTEGATE PRESSURE CONTROL PWM).

How do you reset the engine management light on a Vauxhall Zafira?

An even simpler way to clear the engine management light is to turn the ignition on and off. This approach achieves the same outcome as the previous step, but without disconnecting the battery. Turn the ignition on and off three times, pausing a second between each cycle. The engine management light should go off.

What controls the wastegate on a turbo?

In most cases, a wastegate is a relatively simple valve, controlled by a pressure actuator linked to the boost pressure of the turbo. The wastegate is held shut by a spring inside the actuator, but when the boost pressure exceeds the pre-set maximum, it compresses this spring, progressively opening the wastegate.

What does the engine light mean on a Vauxhall Zafira?

Zafira malfunction warning light If the warning lamp illuminate when the engine is running, there is a fault within the exhaust emission control system. Although not a risk to damage to the vehicle, it may exceed the legal emission limit.
