Hello.

I have problem with my 2007 yaris D4D. I change complete engine, original engine has huge oil consumption but it starting and running ok. New engine is 2005 model, but every parts looks same. When i pull old engine out, i pull ecm wiring connector out.

New engine in, all wirings back. cranks good, but not run, no smoke. Fuel handpump is hard. All grounds are ok and wiring.



Check DTC techstream diagnostic tool

P0340, P0045, P1271, P0089, P1228, P0252

Cleaning DTC:s not possible, they come back.

I wonder if ECM broken? When i pull ECM connector out, battery has allready disconnect.

Will anyone have any opinion on the problem?

Best Regards
Jussi

What are the codes?
not just the numbers, but what does they say?

I'll pretty much guarantee you the ECM is not compatible with the newer model year engine. Yes, they look the same, but electronics not quite.

07 is a nlp90 yaris
05 is a nlp10 yaris

The engines are not the same.
How much did you swap over from your 07 engine?

07 is a nlp90 yaris
05 is a nlp10 yaris

Those are chassis codes, not engine codes. Different chassis models can have the same model engine. I do stand behind my comment that engine management is not the same between the two model years being dealt with here.

This engine is not nlp 10 engine. All components/brackets looks same. Turbocharger is same.

the next option seems to be to replace the old engine electrical components with a new one, or at least compare their part numbers with each other

Problem solved. My mistake, im only measurement fuses continuance. Problem is bad contact and corrosion on edc2 fuse. No dtc and engine run.

thanks to everyone
