The Complete Volvo Fault Code List

When it comes to maintaining and troubleshooting Volvo vehicles, having access to a comprehensive fault code list is invaluable. Reading fault codes is the best way to know the root cause of performance issues, and also essential for maintaining driver safety in heavy-duty vehicles.

Understanding these codes allows for efficient diagnosis and resolution of potential issues that can affect the vehicle's performance and safety. This article will provide a complete Volvo fault code list to help facilitate and simplify your repairs. 

How to Retrieve a Volvo Fault Code

1. Automatically using an OBD-11 diagnostic scanner. 

1. For passenger vehicles and hobbyists, Autel is a great choice for essential diagnostics that blend capability with affordability. It should have all you need.

1. Let us find the perfect Autel scanner for you!

2. For heavy-duty Volvo vehicles, including commercial, off-highway, and marine vehicles, Jaltest is our #1 choice for businesses who manage a large fleet of multi-brand vehicles. Jaltest is designed to work for any make or model, and has tons of capabilities outside of fault code reading, helping you maximize your fleet’s performance and efficiency.

2. Manually using the odometer reset button. 

1. Code will appear on the odometer display in numbers. If not in numbers, then the engine light will flash to indicate a number. 

2. You need to press and hold the odometer reset and trip buttons while simultaneously turning the ignition on. You may need to do this in multiple cycles.

• P0171: Engine problem. The engine is running too lean on the cylinders. Too much air or too much fuel in the combustion mixture. 

• P0200: Problem with the fuel injector. Fuel injector is malfunctioning, clogged, dirty, or having connection/wiring problems.

• P0202: Problem with the fuel injector. Fuel injector is faulty, worn-out, clogged, dirty, or having connection/wiring problems.

• P0300: Indicates a cylinder misfire. Could be caused by worn out spark plugs or ignition wires, bad ignition timing, problems with the MAF sensor, fuel pressure, throttle position sensor, and/or engine.

• P0401: Exhaust Gas Recirculation (EGR) Flow Insufficient. Usually caused by a problem with the EGR valve, Faulty Differential Pressure Feedback EGR sensor, or EGR control solenoid. 

• P0420: Low catalyst system efficiency. Oxygen sensors are not sensing a big enough difference in oxygen levels when going through the catalytic converter.

• P0430: Catalyst system efficiency is below the threshold on Bank 2. Indicates a problem with the catalytic converter or engine efficiency. 

• P0440: Problem with the evaporative emission (EVAP) system. Loose gas cap, fuel tank leak, or faulty component.

• P0500: Problem with the Vehicle Speed Sensor (VSS). Malfunctioning drive gear, speedometer, or transmission. Faulty VSS.

• P0505: Problem with the idle control system or idle air control valve (IAC). Often caused by vacuum leaks, damaged wires/connections, uncalibrated idle speed, or a faulty idle air control valve or powertrain control module.
