Hello all my name is Kelvin and I have a 03 montero sport. I recently changed the timing belt and it crank and run fine for about 3 days. Tore it back down and realized that the crank sensor was damaged. Replaced crank sensor with one from autozone. Truck ran fine for a few days and then it would start and run for about 3-5 seconds then shut off. Had read somewhere that the montero doesn’t like aftermarket parts so ordered a Mitsubishi crankshaft sensor and installed it. Started up fine. Shut truck off after running for about 10-15 minutes now it’s back doing the run then shut off after 3-5 seconds. My question is will a relearn have to be performed for the new crank sensor? Any help is greatly appreciated.
