G'day all,
I am having issues with my patrol, what it is:
2003 3.0L ZD30
Manual
160,000 ks
NADS (Provent Catchcan, Dawes valve, needle valve, blocked EGR, boost + EGT gauge, egt gauge is fitted pre-turbo)
I have owned the patrol for almost a year now and it has always run higher temps. 110k about 14 psi it will sit on 470 (remember that the gauge is fitted pre-turbo so temps should be a little higher), towing an empty tandem axle trailer (~ 500kg). If I hit a hill in fifth gear even with only 1/3rd throttle the temp will rapidly hit 550 i.e. within 30 seconds, it will easily cilmb to 600, at that point I will have backed off the throttle, changed down to 4th and slowed to probably 90k. This is on a moderate incline. I have also found that towards the end of the trip the temps will be sitting slightly higher and will spike much faster.
As well as this my tacho has stopped working, the temps were up before it stopped and haven't changed since it stopped. Every auto elec and mechanic I have spoken to insist that it will be the instument panel itself and just want to take it out and send it to mister nissan to fix. I also get an intermittent speed sensor error showing up (01 04) it usually appears if I am revving hard in 4th, e.g. accelerating to 100 on the freeway keeping it in 4th all the way to 100. after the engine has started and stopped a couple of times the engine light will go out and stay out, it never comes on when just driving around town. I also average about 14L/100
What can I check/do now? I disconnected the crank angle sensor the other day to see what would happen and it threw the appropriate error codes (0407, 0702) crank angle sensor and tdc sensor errors. when I reconnected them the engine light went out and everything was back to normal?
Cheers
Phil
