G' Day mates, we got a strange problem with a TB42:
The problem is to start engine when it's hot or cold too. When cold with the temperature sensor plugged needed 7 or 8 quick contacts on the starter. If the engine doesn't starts it needs to unplug the temperature sensor.
When the engine running its engine revs are under 500 rpm. Then after a moment rises above 1000 rpm and then stabilized at 750rpm when engine hot.
Hot starting with temperature sensor connected is almost always ok but the engine rpm is much under the 500rpm, the engine growls and you have to play with the throttle to get to 750rpm.
When you are moving the engine is fine but after a sudden slowdowns, with heavy use of the brakes or scaling gear, the engine revs drop under 750rpm and if pushing throttle the car doesn't moves, it growls, and it tends to go off.
You have to play with throttle or change in N to have a response of the engine and come back at 750rpm needed to run the car.
The diagnostics checking says always error code 13 = engine temperature sensor circuit.
Replaced one by one the following parts:
- 3 temperature sensor
- 2 throttle sensor throttle body
- 2 airflow sensor
- inlet duct
- auxiliary air control (ACC)
- fast idle compensating device (FICD)
- Fuel pressure regulator
- wiring connectors (all)
- termometer
- ECU
the error 13 still there! (note: all the replaced parts come from another nissan Patrol same model working perfectly).
On the working Nissan has been replaced the components with (supposed) problems coming from the "broken car" and it still to run perfectly.
At the replacement of the ECU the diagnostics test gave code 55 = all ok. But the start was still difficult. Re-checked, after starting, the diagnostics test and reappeared error 13 ....
All the masses of the engine have been checked and are ok.
We worked on (with a friend) for a whole weekend and no solutions...!
A big big thanks to everybody can help us!
