Re: car, motorcycle programming or decoding

check error code, then check live data to see what is wrong, than check on problematic area with multimeter/osciloscope


opel ecu not recieve data from sensor but sensors voltage and wiring is ok?
in ecu is broken wire between ecu board and ecu connector

Please can you give me the Manuel of this particular car Ford Fiesta 2002 1.4dtci diesel

Re: car, motorcycle programming or decoding

you could do with a scanner with live data then you check things better .

It could be the airflow meter at fault, try cleaning it .

I've cleaned the MAF sensor too.please if you think it can be this MAF why the scan is not giving any code related to that?

Re: car, motorcycle programming or decoding

Please can u get me a diagram or a schematic document about the inside of my car?so that I can trace the DPFE

[petehall347]

Re: car, motorcycle programming or decoding

i do not have any pictures .
i would think there is a solenoid valve to check at the other end of the vacuum tube

Re: car, motorcycle programming or decoding

I'm not seeing that DPFE sensor on my car,can u show me some pictures of it on Ford Fiesta vehicle?

Re: car, motorcycle programming or decoding

This is my EGR
My mechano say my EGR is not faulty and we’ve cleaned it and but it back
Please I want to understand something,why my scanner is saying with P0401 code that there is something wrong with my EGR,since my there is no wire connection with the EGR
Please need your explication

Re: car, motorcycle programming or decoding

egr bad or bad wiring .

Re: car, motorcycle programming or decoding

try cleaning it first .
might need ultrasonic cleaner to clean egr valve .

I've cleaned it and scan the car ,still the same code

Re: car, motorcycle programming or decoding

P0401 EGR
P0113 IAT circuit high
P0102 MAF circuit low
P0342 crank sensor circuit low
P0480 cooling fan circuit relay
P0088 fuel rail too high pressure
P0200 injector circuit malfunction .

looks to me like someone has been pulling plugs off and on with ignition on . or battery was maybe very low .
now clear the codes and see what comes back right away .

p.s nothing to do with throttle control according to those codes .

I cleared the codes and this morning I scan my car again therefore the scan gives me only one code:P0401
Your advice please,should I change the EGR or clean it?

[petehall347]

Re: car, motorcycle programming or decoding

change fuel filter if nothing else fixes it .

[petehall347]

Re: car, motorcycle programming or decoding

battery should be 12.6v ish with everything off engine not running .. engine running 13.8v to 14.4v ish .
yes alcohol but spray it in there .do not touch the sensor part as they break easily .
