Engine Warning Light

[Filbee]

This morning the engine warning light came on and the car went into limp mode. Managed to safely pull off the road and turn the engine off. Cycled the ignition to see if the engine warning light was still on permanently - it was. I started the car and was able to drive the car home without any problems. It did not go back into limp mode again during the drive home (5ks). Checked the ignition this afternoon and the engine warning light is still illuminated. Is the car safe to drive, or should I get in touch with MMM (local dealer) to have the car checked out. First time that this has happened. I have about 132,000ks on the clock. I have a ChipIt module, EGR blank fitted and race pipe. Should these be removed before taking the car to MMM? I have had some minor surges from time to time, very intermittant and doesn't last long. Surges don't happen again for several weeks. Always thought it might have been the fuel. Your collective thoughts are very welcome. Cheers Filbee

I think you have code p0299 turbo underboost
If you have egr blank and no hole in the throttle plate

How long have you had the egr blank in for

If youre going to dealer i would recomend to take mods off
Especially if youre paj is still under waranty

Surging sounds more like suction control valve.

Hi Filbee,

I've got the same set up as you. I was getting the engine warning light and limp home mode, occasionally at first and then more often. Throwing the code PO 299 plus another that I can't remember at the moment. I've done just over 160,000.

I had the suction control valve replaced and the manifold etc cleaned out. I've had no more issues. I left all my mods in place as I was out of warranty.

I would strongly suggest that with these type of mods that you have a scangauge as no matter where and when the car goes into limp home mode, you can easily clear them and get back to help if you need to.

Once I had the SCV replaced etc, no more probs as I said but if something does happen in the middle of nowhere, the scangauge tells you what the prob is and may enable you to get home, very important I reckon and great piece of mind.

Col.

I have had all the same problems car is goin in to be sorted tommorow once sorted I'll put my egr delete in to complement exhaust

My check engine light self clears after about 3 or 4 starts during the day, thats with the p0299 code. It still shows the code on the scan gauge tho, but drives mormal.

I experimented with an EGR blank plate a while back and had the same experience. The engine light went off by itself the day after it came on. It probably was after 3 or 4 starts following the original error and limp-home mode happening.

egr blanks

Check around your EGR valve if there are black deposits egr valve is leaking

Also check under lower manifold if there is black oily residue manifold cover is leaking

Thanks to all who have provided comments. Much appreciated.
It would appear that this is a very common issue with the Pajero. Anyway, couldn't get into my MMM dealer until early June. And, the service rep was only interested in whether the tappets have been adjusted in the 112,000 ks that I've owned the car. He did agree that sometimes it could be the Suction Control Vlv or Map sensor, but he still concentrated on the tappets. So this afternoon I took it to the guys that fitted the ChipIt module. Computer spat out a sensor code (PO256), but no engine warning code. He checked the settings on the ChipIt module, all okay. Then removed the sensor on top of the located on top of the air cleaner. Gee, it was really dirty.
He also checked the tube connected to the bottom of the MAP sensor. Now I hope I'm talking about the right sensor - pls confirm that the MAP sensor is sitting up against the firewall, right hand side of engine (looking at it) and has a thin black rubber tube connected to the underside? The mechanic suggested that I throw in a bottle of injector cleaner, which I did. As for EGR blank, I'll have a look tomorrow morning to see if it has any signs of leaking, same for the lower manifold. I have 8,000 ks until the car runs out of warranty, so plenty of time to sus this whole thing out. Again, thanks for feedback. Cheers Filbee

PS. Fitted a set of Philips Daytime Running Lights (4 LEDs per light) to my bull bar. They are illuminated on start up, but as soon as the parkers come on, the DTRLs are extinguished. So my wife is happy that we have some lights 'on' during the day, and I am happy that we no longer dull out the speedo lights and the GPS screen. Turning the DTRL off with the parkers (generally night time) will satisfy the eager constable.

are you sure its po256 i cant seem to find this in the factory manual

It was definitely a combination of those numbers. Thought I'd remember. Should commit things to memory. Try 625 or 652 etc. Thanks pasniny.

Some advice and comments please.

Just got back from a trip and just getting to the end of the freeway entering Adelaide and I notice my engine waring lamp is on.
I then find the car is very sluggish and gear change is also sluggish, I assume this is limp mode.
As I turned engine off it seemed to run on. I left it for a while turned engine back on but when I switched it off it didn't seem to run on.....maybe my imagination.
There certainly was no surging with the car getting home or even prior to that.
I have the car booked at mitsu tomorrow but I would appreciate some comments on what it may be.
I don' have any fault codes but will ask mitsu what codes show when they have a look tomorrow.

From reading some threads I assume the issue could be related to
DPF/Sensor
Manifold/Map sensor
SCV

Am I correct with the above and or what else could have caused this.

Thanks in advance

as listed above; there are a number of faults associated with the Check Engine Warning Light. waite for MM diagnosis .

[kiwi1973]

You say the engine didn't seem to run on the second time you were switching it off. Was the engine light still on after you turned the car off the first time? Perhaps it had reset?

If it were DPF related I'd expect a flashing DPF light also.

Not much more to say without a fault code. I'm currently experimenting with android Torque (the paid version) on my phone together with a cheap Bluetooth ELM327 device from eBay and it has worked for me to retrieve a fault code (and reset the engine check light). Just mentioning this because these days it's possible to retrieve fault codes yourself for minimal cost - even if that doesn't necessarily mean you can do something about it yourself.
