DPF temperature sensor
 

Hi All, I have a 2015 Outlander III 2.2 d.
Following issues with lack of power, smell and economy and found a split in the intercooler pipe. I replaced this and thought I'd remove and clean the EGR (for the smell, you never know...)
Problems remain and long story short it transpires the CAT had basically 'crumbled' inside which led to the DPF clogging - or so i'm told.
Had the DPF and CAT removed, cleaned DPF and got a CAT from the breakers. Now I am having problems sourcing a temperature sensor for the DPF. The OEM part is 1587A120 and when in stock retail for around £500. This on top of £350 for the CAT + £??? I owe the mechanic for removal, cleaning etc..
Has anyone had similar issues and is this the only part that will fit as it seems I'm still weeks away from one being available?

Thanks for reading 👍

Summary of Events – Mitsubishi Outlander

1. Initial Problem – Intake Hose
   I first experienced a sudden loss of power and heard a hissing noise from the engine bay. On inspection, I found a cut intake hose. After replacing it, the car regained full power and responsiveness.
   • The car then drove perfectly for about two weeks before any further problems developed.
2. Tried a DPF Spray Cleaner
   
3. Before using any fuel additives, I tried a DPF cleaning spray applied directly into the top of the DPF. This did not make any noticeable difference.
4. Tried a DPF Spray Cleaner. Before using any fuel additives, I tried a DPF cleaning spray applied directly into the top of the DPF. This did not make any noticeable difference.
5. DPF Warning Appears
   After roughly two weeks of normal driving, performance dropped again and the DPF warning light came on. At the same time, the turbo began making an unusual whirring noise, different from its normal whistle.
6. Tried Fuel Additive Cleaner I then added a DPF cleaning additive to the fuel. At first, performance improved, but by the second day the car was much worse — very restricted with little acceleration.
7. Highway Incident While driving on the motorway, a DPF pressure sensor pipe came loose, confirming there was excessive exhaust backpressure.
8. Inspection of the DPF I removed the DPF and found broken and melted pieces of the filter inside, showing the filter had overheated and collapsed. When I shook the exhaust, I could also hear loose debris further downstream, but I didn’t remove them as they sounded too large.
9. DPF Replacement I replaced the DPF filter with a new unit. However, the car still showed fault codes and continued to feel restricted once warmed up.
10. Current Symptoms
    • On cold start, performance is acceptable (a little sluggish but still responsive).
    • After 15–20 miles, when warm, performance becomes much more restricted — revs build slowly and acceleration is poor.
    • The turbo whirring noise has stopped.
    • Occasionally, when warm, I feel a slight jerk or hesitation, subtle but noticeable.

Any help or advice will be appreciated.Thanks

Hi
Did you find the sensor 1587A120, also looking for the same?

Thanks
