How to fix engine fault code P0089 on L200 DiD triton

Error Code P0089 Fuel Pressure Regulator 1 Performance

code p0089 refers to fuel pressure regulator---performance problem===causes --fuel pressure regulator--- mechanical fault
check the regulator operation as it controls the operation of the fuel pump as well
At this point I would be considering a new regulator or checking any wires connected to it

code p 0089 refers to fuel pressure regulator---performance problem===causes fuel pressure regulator---mechanical fault
code p 1275 refers to heated oxygen sensor (HO2S) 1--response time===causes--- HO2S--fuel pressure--injectors--intake air leak--exhaust leak--MAF sensor
as the pressure regulator ( fuel pressure) appears in both codes I would be paying attention to that unit first

Hi there, 6 years later i ask you, did you solve the problem? thanks

Spark plug gap does not effect the engine timing so it's not that critical. Thirty 5 (.035) should work just fine.
Otherwise consult a service manual fro your model or call a Mitsubishi service centre

I would need to know what year model this is, engine capacity and engine code to confirm but generally on the x-trails that fault code refers to a mechanical fault on the fuel pressure regulator. This is for the YD22DDTi engine.

This is an indication that the TCM is not function properly As it is an automatic the gears in constant mesh with gear changes being effected by clutch packs and bands so the ratios are always correct just the selection is not working properly./ Hence the TCM fault.

the Mitsubishi Triton is also known as the L200 try looking for manuals for L200 for 1996 year.
Manuals from Haynes of the UK or Chilton are some of the best.

fault p0089 and lack of power

Diagnostic trouble code P0089 - The ECM commands the Bosch high-pressure fuel pump to deliver a specific fuel rail pressure - that can vary up to 23,000 psi depending on load and speed. The actual pressure is monitored via the fuel rail pressure sensor. If the fuel rail pressure varies more than desired or if commanded fuel pump flow is 100mm3/second or less, DTC P0089 will set.

Corrective action includes measuring the fuel rail pressure using a Tech II scan tool, then compare that to commanded fuel rail pressure with the engine running at 2000 rpm. The difference must be less than 20 Mpa.

A blockage in the fuel tank or plugged fuel filter could cause this fault (excessive vacuum in fuel line). If there is less than 5 in Hg of vacuum when measured at the fuel pressure test port at 3000 rpm, the fuel pressure regulator could be defective, and may need to be replaced. The fuel pressure regulator (FPR) is a sub assembly located on the Bosch high-pressure fuel pump.
