New Manifold & MAP Sensor

[Landfish]

Hey,

Just looking for some advice from people who have had the manifold on their NS Pajero replaced under warranty. Has anyone had the MAP sensor replaced under warranty at the same time or shorty after?
I have just had my manifold replaced as a 'good will' warranty last week (car is out of warranty by a month) and it is still playing up. So they have told me the MAP sensor requires replacement, but it won?t be covered under warranty. I have asked them to talk to MMA about getting it through warranty as I feel if the manifold problem has damaged the sensor then it should be replaced as part of the same claim. Apparently MMA originally rejected the claim for the sensor when the manifold was replaced because only a few require the MAP sensor replacing. MMA have not rejected the new claim yet, I am just trying to further understand what I am talking about.
As im not very mechanically minded I am just looking for some advice...
Firstly am I right in thinking the MAP sensor will be damaged by the dirty manifold?
Has anyone had the MAP sensor covered by warranty outside the 5 year warranty?

Thanks for any help.

Had both the manifold and MAP sensor replaced at Easter. My car was 348km out of warranty but both replaced without cost. The MAP sensor at the time was choked up with soot from the manifold so both got done.

Stick to your guns and try for the new sensor. As the sensor is directly connected to the manifold (Manifold Absolute Pressure sensor) it may have been damaged due to its poor placement. I may be wrong but I think most manifolds that get changed have the sensor replaced as well.

Good luck with it.

Landfish, what caused you to have the Manifold changed in the first place? Was it loss of acceleration at high speed......100kl/hr or faster? Because I have noticed that my NS has a minor hiccup at around 105kl/hr. Whilst I describe it as a minor hiccup, some might suggest that it is a slight loss of acceleration, but it happens so quickly (less than a second), that it doesn't interfere with the acceleration. If somebody out there can suggest what the problem is, I'd be much appreciated. Another NS Pajero owner said to me to take the car back to Mitsubishi and have them test the car, but most likely it would be the manifold, map sensor and another item that I can't recall right now. Thanks in advance.

Mine is being replaced on the 17th and only because I ask them to check out the rough idling last service. Th report showed that it was surging and that a flash burn was preformed. I received a phone call (some weeks longer) saying my part (intake manifold) had arrived when can I book the car in.

A bit confused as I thought that this was an automatic hot fix on your next car service. The car was bought in 2008 and reaching the end of it's warranty (I picked up the car in Nov 11) now I am wooried at what other hotfix's have not been done.

Noted you mentioned surging as an issue; I put up with this type of condition for weeks with occasional P0299, P0107 and lastly a P0089 error which for a Mitsubishi is a ?Suction Control Valve Stuck? error condition. The SCV was replaced after this issue under warranty. The vehicle has been running like a dream ever since. I also had the Manifold and MAP sensor replaced earlier in the piece (year ago). My vehicle has a DPF delete pipe, Chip it module and full blanking plate. Not one error now for 4 months. Suggest you may also consider the SCV if no other solution is found.

Delete pipe chipit & blanking plate do you get
P0299 every now & again ir have u drilled 12 mm in burterfly
Valve if so does the engine runon when switched off

Thanks

I considered drilling the 12 mm hole but since the SCV has been replaced no errors. In the past an occasional P0299 was easily cleared with my scangauge 2 which I have permanently mounted. I have been reluctant to pursue this modification as it is irreversible and would be an issue for any warranty claims. Only have a few months of warranty remaining so if the P0299 starts to be too regular still could be an option I would pursue in the future once warranty is expired.

My Manifold was orginally replaced due to a check engine light, When it occured the car surged the went into limp mode (if i remember rightly i believe the traction control light came on too). I just happened to be due to take it to the dealer that week for its service. When i picked it up i was told it was due to a dirty manifold and they have asked mitsubishi for a goodwill warranty claim.
After they replaced the manifold the problem was still there, This time i was told it was due to a 'turbo low pressure' error... They said could be one of two things causing it, Firstly the MAP sensor and then VGT solenoid (i think). They recommended only the MAP sensor for now.

I heard back from them yesturday and MMA has agreed to replace the MAP sensor and VGT solenoid parts under warranty. I am still going to have to pay about $400 labour to get them fixed.
Apparently the Solenoid need to come from the eastern states so i need to wait till next week for the replacement.

Thanks for everyones help.

Esteban - did you have the Chip It Module, Delete Pipe and EGR blanking plate fitted when you had the Manifold and Map sensor replaced? Or did you do the ChipIt mods after the Manifold/Map sensor replaced? Reason I ask is; I have the same ChipIt mods as you, and I'm wondering whether I need to remove the module and delete pipe before taking the car back to Mitsubishi to investigate a small surge that I get at speeds above 110 klms/hr. Not sure how Mitsubishi will react if I present the car for service/warranty with the ChipIt gear still fitted to the car. Looking forward to hearing from you. Cheers Filbee

Return it all to standard give them nothing to get out of a problem Mitsi's engineers created.
