Hello All.
Been through as many discussions as I can find and nothing that resembles this issue. I have a ZD30 direct injection Nissan Patrol. Started it, reversed it out of the garage went to go forward and bang, straight to limp mode. Checked the fault code with ECU talk. Indicated that it was Throttle Positional Sensor. OK, replaced the sensor making sure the OHMS setting was at .5 as per manual. Disconnected the battery overnight and refitted the peddle. The engine starts no worries. However, engine goes into limp mode once the engine revs above 1600 rpm. If I pump the accelerator as though it's a petrol engine trying to start cold, it will rev right up to 3 to 4000 rpm. Only problem is it will only run for a few seconds and cut out as though I turned it off. If I start it again, it starts perfectly but still won't go past 1600 rpm. When it stops the ECU Talk indicates that it is the TPS again. Any help would be appreciated.
Regards homebrew.
