Hi all
Have been stalking this forum for the past week in an attempt to solve the following intermittent problem. Sorry about length of post.
Vehicle Navara D22 ZD30 motor.
The problem is an intermittent one and has been occurring for nearly 2 weeks. The vehicle will travel for nearly approx 11 km and then go into limp mode with MIL on and zero tacho reading.
Have extracted the codes 0702 and 0407 which according to the manual are P2 TDC Pulse Sig and Crank Pos Sen (TDC).
The following procedure was taken on test run.
1: Clear codes
2: Travel at between 80 and 100km per hour.
3: At approx 11km engine in limp mode zero tacho reading.
4: Stop and Read codes, result = 0702 and 0407
5: Clear codes
6: Restart, engine revs up by itself MIL back on.
7: Wait approx 5 mins restart MIL is off
8: Travel back home without incident.
9: Read codes result = 0407
10: Leave car to cool down for 2 hours.
11: Clear codes
12: Perform the following procedure taken from manual.
WITHOUT CONSULT-II
1) Turn ignition switch “ON” and wait at least 2 seconds.
2) Start engine and run it for at least 2 seconds at idle speed.
(If engine does not run, turn ignition switch to “START” for at
least 2 seconds.)
3) Turn ignition switch “OFF”, wait at least 5 seconds and then turn
“ON”.
4) Perform “Diagnostic Test Mode II (Self-diagnostic results)” with
ECM.
5) If DTC 0407 is detected, go to “Diagnostic Procedure”, EC-882.
If DTC 0702 is detected, go to “Diagnostic Procedure”, EC-899.
Check code Result result = 0505

1) Turn ignition switch “ON” and wait at least 2 seconds.
2) Start engine and run it for at least 2 seconds at idle speed.
(If engine does not run, turn ignition switch to “START” for at
least 2 seconds.)
3) Keep engine speed at more than 2,000 rpm for at least 10
seconds.
4) Turn ignition switch “OFF”, wait at least 5 seconds and then turn
“ON”.
5) Perform “Diagnostic Test Mode II (Self-diagnostic results)” with
ECM.
6) If DTC is detected, go to “Diagnostic Procedure”, EC-923.
Result from checking codes = 0505 (No DTC)
Any suggestions on further testing would be greatly appreciated.
