Question about Mitsubishi Montero

2 Answers

Hi, I have recently acquired a Japan import Mitsubishi Pajero 2000 model, Engine 4M41 turbo diesel. The motor starts and runs fine without any problems noted. However any time I stop at junction or off the lights, the vehicle idles ok but on taking off there is a 5 to six seconds non response from the throttle no matter how hard i push the accelerator. Thereafter the engines picks up and moves on ok. This is quite hair rising since the car just rolls into the junction and can be easily hit by an oncoming car. Kindly assist.

The behaviour of the car is a clear indication of turbo pressure failure and the error codes support that:
CAN COMM = communication error in the sensor network.
VGT CONT. PRS. = the solenoid that controls the turbo's pressure is faulty or the pipes that connect to it are shot
EGR POS. SNSR = the vacuum sensor is defective.
Check all the air pipes for leaks - replace if necessary. The replace the vacuum sensor and control solenoids, located on top of the engine, drivers side between bulkhead and inlet manifold.

1987 Mitsubishi Pajero 2.5 turbo diesel not starting


Hi, there is a little cable that in on the starter motor, probably you have just disconnect it, it happens to my pajero lot of times. look around the starter motor for a cable that is not going somewhere and then locate the little connector on the top and rear part of the starting motor. if this is not the case then try another battery, pretty sure one of the two is the problem.
