Mitsubishi Triton: Suction control valve (SCV) failure from dirty fuel, P0089 limp mode (3.2 4M41 diesel)

Suction control valve (SCV) failure from dirty fuel, P0089 limp mode (3.2 4M41 diesel) is a common engine fault on the Mitsubishi Triton on the 2006–2009 cars, and we rate it major. Putting it right costs $400 to $3,500 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 35 documented faults on the Mitsubishi Triton.

What you are looking at

No photograph available

We do not hold a verified photograph of the High-pressure fuel pump or Fuel filter yet. We would rather show none than show a picture of a different part.

What goes wrong

The 3.2 4M41 diesel in the ML Triton is known for suction control valve (SCV) problems on the high-pressure fuel pump, usually triggered by dirty or contaminated diesel. Typical signs are a loss of power between about 1800 and 3000 rpm under hard acceleration, surging, higher fuel use and limp mode with code P0089. Replacing the SCV and fuel filters usually fixes it if the pump itself is not damaged.

What you would notice

Flat spot or loss of power between about 1800 and 3000 rpm
Surging at steady throttle
Higher fuel use
Limp mode with engine light, code P0089

How to check it

Where to look. Engine bay, high-pressure fuel pump

On the test drive accelerate firmly through 1800 to 3000 rpm and feel for a flat spot or surging. Check for an engine warning light. Ask when the fuel filter was last changed and whether the SCV or pump has been replaced. If a workshop inspection is possible: scan for P0089 and compare actual and target rail pressure.

Parts involved: High-pressure fuel pump, Fuel filter.

What it costs to put right

$400 to $3,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the suction control valve or fuel pump been replaced?”
“Has it ever gone into limp mode?”
“When was the fuel filter last changed?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Mitsubishi Triton buyer questions

Is suction control valve (scv) failure from dirty fuel, p0089 limp mode (3.2 4m41 diesel) serious on a Mitsubishi Triton?

We rate it major and common on the Mitsubishi Triton. The 3.2 4M41 diesel in the ML Triton is known for suction control valve (SCV) problems on the high-pressure fuel pump, usually triggered by dirty or contaminated diesel. Typical signs are a loss of power between about 1800 and 3000 rpm under hard acceleration, surging, higher fuel use and limp mode with code P0089. Replacing the SCV and fuel filters usually fixes it if the pump itself is not damaged.

How much does it cost to fix on a Mitsubishi Triton?

$400 to $3,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Mitsubishi Triton years are affected?

Our research records this fault on the 2006–2009 Mitsubishi Triton. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
