Mitsubishi L200 2.5 2003 - Loss of power, code 52 #

Posted by Dave Emm on May 22, 2012, 7:05 pm

Year of Manufacture *: 2003
Engine Size and Code *: 2.5 4D56T

This vehicle starts and runs fine when cold, but when it gets hot the MIL light comes on and it goes down on two cylinders, actually stops injecting. Is this Mitsubishi's version of limp mode?Fault codes are 52 boost sensor and 00 ecu failure. Have actually fitted new boost sensor after checking all vac pipes. Seems very odd that a conventional pump (albeit electronically controlled) can stop injecting on two cylinders. According to Autodata its a Bosch pump but it looks more like jap equipment to me. Any clues? Cheers Dave.

Is the crank sensor and reluctor ring ok?

I have had very weird things with these, you may be aware the bottom pulleys come loose, I've had two now that had come loose before their first cambelt change, and where there was supposed to be a groove in the reluctor for the crank keyway it had worn a slot, causing very odd running conditions and misfires etc as the reluctor jingled around.

Not quick and easy to check , but something I have spent hours chasing.

Spot on info Liam. Crank pulley didnt feel loose on first inspection, but when I started strippng out found that the centre bolt only took about 20nm to undo. The crank pulley is ruined and the crankshaft itself has a big gouge in it. The front half of the front key is almost worn away to nothing and the reluctor is not only badly worn but also badly corroded on its inner diameter.The pick up is also damaged. Cant thank you enough for your help, recovery truck was booked to take it to nearest diesel specialist 30 miles away. Thanks again, Dave.
