Mitsubishi Triton (L200) Fault Codes

About the Triton (L200)

A compact pickup truck, the Triton was launched for the first time in 1978 and was built by the Japanese company Mitsubishi Motors.

First generations sold under many names such as the L200, Mighty Max and the Forte, and Mitsubishi enjoyed greater success with the vehicle outside of the domestic market.

Starting life as a two-wheel drive vehicle, four-wheel drive was added three years later and other mechanical features included disk brakes, suspension with coil springs and recirculating ball steering.

By 1986, Mitsubishi began sales of the second generation, this time two body types could be purchased, a 2 door or four-door pickup, this obviously had greater appeal as it could now seat a family rather than just two people.

The latest generation, the fifth, was released in 2015 and was powered by a brand-new 2.4-liter diesel engine. Having been constructed in multiple assembly plants previously, these new vehicles were only built at the Laem Chabang Plant in Thailand and the Catalao Factory in Brazil.

Engine sizes ranged from 2.3-liter up to 2.5-liter diesel with just one petrol, a 2.4-liter; all of which could be mated to either a 5 or 6-speed manual transmission or a 5 or 6-speed automatic.

Operators can see the following error codes when alerted by the engine warning light:

• P0089 – Signaling a problem with the fuel pressure regulator.
• P0093 – A large leak in the fuel system was found on the high-pressure side, driving should stop immediately and a mechanic consulted.
• P0638 – This fault code suggests a diagnostic problem with the throttle actuator control, it is outside of the desired range and needs a specific diagnosis from a garage.
• P0106 – This shows a problem with the MAP circuit.
• P0234 – There is a dangerously high boost pressure reading, a level far above the manufacturer’s setting.
