Greetings all,
I have a 1.9JTD punto from the year 2000 and i recently noticed a problem.
One day on my way to work i noticed that the engine light had turned on and off ( just for a couple of seconds ) twice on that ride.
I didnt noticed nothing different with the car.
The next day the engine light turned on and off many times and this time i noticed that the car sometimes looses power...like no turbo...
I ran the diagnosys and got the following errors:
P0404 ( EGR device (5) invalid signal )
P0236 ( Boost pressure (2) invalid signal )
I was wondering if this can be wirering problems since i get invalid signal or some bad sensor.
I am not considering a hose problem since it's an on and off problem although is getting more frequent.
How can i troubleshoot this problem?
Is there a tip for testing the sensors ( and which ones ? ) ?
I thank you in advance
Regards
Rui
