Zafira fault codes: Engine management light reset for Vauxhall Zafira

The car’s onboard problem diagnosis system displays trouble codes. Vauxhall automobiles are notorious for having them. These error codes can be caused by various issues, including intermittent failures, defective sensors, damaged cables, or general engine management system damage.

When you notice fault codes on your dashboard, it means your car isn’t in perfect working order and has to be serviced. If you do not investigate the fault codes and they persist, your vehicle will be harmed and eventually come to a halt.


Fault codes could lead to safety concerns for the vehicle and driver, not just make the vehicle stop working. As a result, whenever you notice fault codes on your vehicle’s dashboard, you should carefully check and examine them.

Fault codes are indicated by the car’s onboard fault diagnosis system. They are ubiquitous with Vauxhall vehicles. The faults that cause these fault codes range from intermittent faults to defects caused by faulty sensors, broken wires, or general damage to the engine management system.

What are the fault codes?

When the engine management system in your car detects an issue with one of your engine sensors, a Zafira fault code, also known as the Vauxhall Zafira engine management light reset fault code, is displayed.

As a result, the check engine light will illuminate. The Vauxhall Zafira engine management system is meant to self-diagnose malfunctioning systems in your car.


DTC issue codes are Zafira fault codes. They’re generic OBD2 fault codes that may be used to diagnose issues in any vehicle. There are more than 4,000 generic fault codes separated into three categories.

The different classes are used for other components in your car. Zafira fault codes are for vehicles built mainly between the years 2001 and 2007. The system monitors several systems on vehicles with the Delphi engine management system.


Zafira ECU fault codes can be hard to identify, but they are there for a reason. These little error messages will help you diagnose problems with your vehicle’s computers and can even help prevent them from occurring in the future.

Zafira fault codes are similar to Zafira check engine light or Zafira immobilizer fault codes. For this reason, the Zafira fault codes are identical to those of the Chevy Cobalt. They use the same On-Board Diagnostics (OBD-II) system. The engine needs to run for them to perform a reading, so if you want to troubleshoot your car while it is not running, you need a special OBD-II adapter.

What does the engine management light mean on Vauxhall Zafira?

The engine management light is a warning light that indicates a problem with one or more engine components. For example, turning the ignition on and off three times in fast succession might check the engine management light (also called the service engine soon light, check engine light, MIL, MEL, or ABS/airbag).

The engine management light, sometimes known as the check engine light, is a group of lights. The first one, which most people are acquainted with, indicates that the car’s emissions system is malfunctioning.

This does not necessarily imply that the vehicle will emit dangerous pollutants; rather, it signifies that its computer has identified something unexpected in the exhaust.


The other lights usually indicate problems with the car’s engine management system. The management system regulates throttle response and idle speed; it also controls the engine’s idle speed when the vehicle is not moving, reducing pollution caused by idling.

Other lights on the dashboard are part of other systems. So, for example, if you see an anti-theft light or a door open light, this indicates that something is not as it should be with either your car’s ignition system or its door locking mechanism.

What can cause the engine management light to come on?

Your engine management light might come on for a variety of reasons. Worn-out fuel injectors, a malfunction in the engine control module (ECM), or a broken oxygen sensor are the most common causes of the engine management light turning on.

A blocked fuel injector can cause the engine management light to illuminate, usually after the automobile has been driven hard or rapidly. The engine management light illuminates when a defect in the car’s engine management system is identified.

Other causes of the engine management light coming on are:

  • A fault with one of the engine sensors
  • Including the air mass meter.
  • Crankshaft position sensor
  • The camshaft position sensor
  • Throttle position sensor
  • EGR valve failure
  • Vacuum hose leak
  • Malfunctioning DPF
  • Catalytic Converter issues, or manifold absolute pressure sensor.

In addition, there are several other causes of the engine management light coming on, which are not covered in this article.

Common causes of the engine management light on and each of the Zafira fault codes

The common causes of the engine management light coming on and their specific fault codes are listed below.

  1. Blocked fuel pump with the fault code P0087
  2. Contaminated catalytic converter with the fault code P0420
  3. A loose filler cap with the fault code P0457
  4. Fuel injectors that are clogged with the fault codes P0171 and P0174
  5. The ignition system is faulty, with the fault code P2335.
  6. Vacuum hose that is leaking with the fault code P0436
  7. faulty exhaust gas recirculation valve (EGR) with the fault code P0401
  8. Oxygen sensor that is faulty with the fault code P0131.

Vauxhall Zafira engine management light reset: how to reset spanner light on Zafira

One of the most prevalent warning lights on the dashboard of a Vauxhall Zafira is the spanner light. The spanner light on your Vauxhall Zafira’s dashboard is a warning light. It might signal a problem with your car’s numerous systems.

The engine management light shows that the engine management system is malfunctioning. The spanner light must be reset if the tag on the air mass meter fails to respond, causing the engine computer to display a failure code and the spanner light to activate.

Quick tip

To reset the spanner light, unplug the vehicle’s battery wires first. Then you disconnect the battery lines from your car. To accomplish this, use a wrench to separate the negative and positive cables. Next, drain the battery’s power. Finally, for approximately a half minute, keep your automobile horn on.

Then disconnect the battery wires for roughly 15 minutes before rejoining them. Finally, check the error codes to see whether they’ve been reset. The engine management light will turn off after you’ve finished. If the light comes back on, though, it means there’s an issue that has to be addressed by your technician.

Common Vauxhall Zafira fault codes list and their meaning

Before we look at the most common Vauxhall Zafira fault codes, let us know what Vauxhall Zafira fault codes are.

What are the Vauxhall Zafira fault codes?

Vauxhall Zafira fault codes are stored in the memory of the system to protect the engine control unit. They are usually in alphabetical order, although in some cases, they may not be.

At one point in time, they were in numerical order, which is typical for older vehicles. A fault code will not always mean there is a problem with the car, but more of a reason to find out the cause of the code and fix it if need be.


Each Zafira has its own set of issue codes that you’ll need to be familiar with to test it. The error codes are stored in ROM memory on each Zafira, which means that the information is lost when the battery is detached.

The fault codes are also recorded in ascending order, which might be helpful if two or more defects co-occur. Like many other vehicles, the Vauxhall Zafira has an onboard diagnostics system that includes a problem code reporting system. Fault codes generally contain a prefix alphabet and are 1 to 4 digits long.

In the computer dashboard memory of your Vauxhall Zafira, there are many error codes. The saved codes on your dashboard may be erased if your battery is disconnected. The following are a few of the more prevalent ones.
