Fault code 65535 / blink 1111

[jade]

Can anyone one please give me a bit more info on this code

Faulty control unit j220 would that be the ECU ?

-Earth connection to J220 contacts 10,14,19,24 that would be the 55 pin connector

ECU has a earth strap with a good connection

Thanks Wayne

Check earths on the inlet manifold are clean and tight.

Help with fault codes

Check earths on the inlet manifold are clean and tight.

I will do, but i did pay attention to these when connected wiring

Also showing 00519 2222

And 00514 2212 g69 tried the tests on it looks ok the zt-2 show voltage going up & down.

The zt-2 read,s 100% closed & 5% fully open is that right thought it would be the other way round

Thanks

Checked earth's all good, checked pins 10 14 19 24 on the 55 pin connector they all earth to the body so they look ok

Any advise on the other faults codes I have would be appreciated

2212 / 00518

2222 / 00519

Thanks

00519 is : internal ECU pressure sensor fault

00519 - VAG1551/2 Fault Code Number
ECU Internal Pressure sensor (G71)
Pressure sensor defective,
Repair or replace ECU or replace internal pressure sensor

00519 Manifold Absolute Pressure Sensor

- Signal too low

- Signal too high

- Control difference


00518 has to do with TPS. is that wired properly?

g71 would be the map sensor strange it worked fine before i will double check all vac lines

I have 5v at the TPS resistant looks ok

But i did just measure 3.8 with throttle fully open on pins 2 & 3 that could be the problem there i will double check this.

Thanks for your input

Ok TPS have 5v on 1&2 2&3 have 3.6 going out' So this hopefully is the problem change switch

What voltage should they have when its at WOT?

PIN 2 - 3 + 4.6v full throttle

I Have finlly got rid of most of my fault codes

Today when i pulled the codes I got 65535 / 1111 & 4444 which is no faults to show that was first then followed by 1111

I have tested the pins on ecu 10 14 19 24 seems to earth well, because of my Furans i had to change the location of earths one is on the cam cover & the other is on the last inlet manifold bolt firmly done up.

Any ideas please on this, because i am keen to remap but need to get to the bottom of these fault codes first.

Thanks Wayne

Has the ECU been remapped already ?

If so - there is a good chance that a bad checksum is throwing up this fault code...

No car has not been mapped yet, Hoping to do that soon

Mmmm - thats normally the cause of 65535 - that or certain MAP failures inside...

Map was fine before strange if it's just given up now

I am presently running on a comp ct 458 with the old chips, would this do it ???

Nope - that doesn't have anything related...
