engine cuts off

[Saeed]

Saeed again,

Some additional information of late...

After the mechanic's check-up and replacing the Mass Air-flow (MAF) Sensor I ran the engine on idle for a long time, and it ran fine. I even rev'ed up to 3,000 - 4,000 RPM for several seconds and it ran fine.

The check engine light did indicate CPS issue after the first repair in 2013, but went out by itself after driving for a little while.

Good evening Saeed and seasons greetings to you too, hope the weather is better in NZ.
I've not had much experience with the 3.0litre only what I've heard on here but I have to say you've had an awful lot wrong with your truck which seems unsual.

If it's any use take a look at a thread called HarlowMavericks motor started by Solarman. His 3.0litre had running issues that Solarman managed to resolve. I'm sure Solarman will on here later as he's a regular so won't be too long.

Good luck and I'm sure you'll get it sorted.

PS welcome aboard:thumbs

The IP on your engine has its own processor and is a known problem as the solder joints fail, but first I would change the ckp sensor as this is a coil around a magnet and with heat a broken wire will cause it to go bad but reconnect when cold, this is the cheaper option as a pump is expensive, you may be able to prove this yourself if you have an ohm meter, the ckp should read around 1500 ohms try it when the motor fails if you get substantially less then you have found the problem, Rick

Hi Rick,

Thank you for the quick reply and suggestion. I read PAPIN's thread and CLIVVY and your suggestions on the same remedy. I noticed that the wire connector to the CPS did not snap-fit but comes off with little pull. I am assuming CKP and CPS to be the same sensor. But what is IP...perhaps internal or ignition processor?

I will give your solution a try, and replace the CPS sensor.

Thanks a bunch, and happy new year!

Saeed

They are referring to the injection pump with ip.

Thanks Blocky I forget that peeps are not up together with abbreviations, Rick

Happy New Year Gentlemen, I put the multi-meter on the CPS and noticed 1,290 Ohm resistance. I also rev'ed up the engine with the CPS disconnected, and it ran fine...I guess it either ran on default or used CAM Position Sensor.

The engine still stalls when it is heating. So what do you all think I should do?

Thanks,
Saeed

Replaced CPS Sensor...engine still stalls while driving

Hello,

The mechanic put a flashy engine fault-code reader, and said it was the CP sensor that was faulty, so I replaced the CP sensor. it ran fine for a couple of weeks (after burning the white smoke off) but when I took it for a long drive to Auckland (200 Km) the engine cut off and stalled again on the way back from Auckland. I had to get AA to haul my vehicle home.

Also, noticed that right after engine cuts out, it hesitates to start and even does not crank even though the starter motor is cranking. But when it does start again the exhaust gives out a lot of white smoke.

I am wondering if it is a fuel line issue such as dirty manual pump filter, etc. although the filter was replaced last Pctober (2015). I did put some fungicide solution recently in the tank to clear an diesel bug that may have developed over time.

The last time fuel line fault code did come up but the mechanic suggested replacing CP sensor first.

This is very troubling, especially, the family saying I should write off this vehicle after spending so much.

What do you think is going on, gentlemen?

Thanks,
Saeed

I am having similar issues, put the lappy on it and ckp sensor multiple times so fitted a new one OK for a day or so then back to same old problem but one day it started hunting at idle, found if I moved the ckp connector plug I could make it idle OK so pulled plug apart cleaned it up and back together, still the same, as a short term fix I have jammed the wires and plug in between the heater pipes this seems to have stopped it for now, so soon as I get time I will be stripping the loom to look for a connection issue, this is a Zexel set up by the way ckp on timing cover, Rick

Hi Rick when I did mine I had same problem, found there was a broken wire right at the original connector plug, so I cut both original plug & socket off & replaced with new waterproof connectors, all good after.

Re: Nissan Terrano ZD30 DDTi 3.0L Diesel

Finally, there is only one fault code (73) after replacing the CPS sensor. My Mechanic checked the fuel filter/manual pump for pressure and flow, in case there was some blockage. No problem there.

He also checked the connector/connection from main ECU to the pump connector (but not the wire/connector going into the Injection Pump).

I spoke to the Bosch Diesel Service guy who serviced the Injection Pump 2 years ago, and he said it may not the the IP ECU (replaced at last service and re-programmed to communicate with main ECU, and it ran fine for 1.5 years), but the wiring between IP and main ECU.

He said the wiring/connector may have been messed-up due to heat when the head gasket and cylinder cracked the last time (fixed since then). He said to check that connection before thinking about repairing the IP ECU or wiring inside.

What do you think?

Not sure if you all are familiar with this diagnostic tool:

the above link does not load, but 73 is communication error to the pump ecu, so yes check all the connectors and wring as thoroughly as you can, dose the engine run? if so how well/bad, Rick
