Mitsubishi RVR/ASX Fault Codes

About the RVR/ASX

The RVR is currently a subcompact crossover SUV designed and built by Mitsubishi Motors.

First sold in 1991, early models were marketed as the Mitsubishi Space Runner and featured a sliding door.

Available to purchase as either a front or four-wheel drive, the RVR was constructed like a minivan and due to its bulky size could not be classed as a compact car in Japan and subsequently suffered a higher tax band.

Today, the RVR faces competition from several popular heavy weights including the Honda CR-V, Subaru Forester, Suzuki Escudo and the Nissan Rasheen.

The Mitsubishi RVR can display a number of error codes throughout its lifetime, some of which are:

• P0420 – This error code can be caused by a number of problems ranging from a damaged exhaust manifold to damaged oxygen wiring. Drivers usually are quick to investigate as it’s a fault code that will trigger the ‘check engine warning light.’ Continuing to drive the vehicle under these conditions will inevitably lead to seriously damaging the catalytic converter which in turn can lead to other problems with the engine in a domino effect.
• P0868 – Transmission fluid issues lead to this code. Used to lubricate the transmission, if there is too little, elements will start to slip or the engine will overheat. This can happen through leaks in the system and is an extremely serious issue. Mechanics will work through a number of fixes to try and find the root cause including replacing the transmission temperature sensor, repairing the transmission itself or searching for the leaks within the system.
• P0171 – A common fault code across all makes and models, this suggests that there is either too little fuel in the exhaust or too much oxygen. There can be a number of causes for this code, which makes diagnosing it difficult. Reasons for this code displaying could include a blocked air filter, a broken fuel pressure regulator, a vacuum leak or fault oxygen sensors.
