Engine Management Light - Error P1204

[Whapter7171]

Hey all

The problem:

Today after starting the car after work, the EML came on (amber), car would now rev higher than 1500 rpm and sounded like it was running on 2-3 cylinders. I have had this problem before a few times, all I have had to do is turn off the car and wait a short time and fire it up again, problem then goes away (for a while)

Today however, the problem seems to be really bad, it took me 3 attempts to drive about 22 miles. That is the bizarre point, I can inbetween the EML being on, drive quite normal.

The car will occasionally jump, the best way I can explain is when a petrol car would misfire and there is a hesitation. Sometimes this happens on acceleration or deceleration.

Also now noticed that the traction control light is also on, however now the EML is red no longer amber

I spent £30 and called a mobile diagnostic technician. Found the following error codes:

P1204 - Injection circuit open/short circuit cylinder 4

General failure information - no sub type information

U0405 - Invalid data received from speed control module

General failure information - no sub type information

U0401 - Invalid data received from engine control module/powertrain control module

Algorithm based failure - event information

B112B - Steering wheel module

General failure information - mechanical failure

U0010 - Medium speed CAN communication bus

General failure information - no sub type information

U0199 - Lost communication with door control module A

General failure information - no sub type information

U0200 - Lost communication with door control module B

General failure information - no sub type information

So he has cleared all the codes for me and suggested I get the P1204 injector issue sorted, may need a new injector and coding or a refurb and coding. Also said I had a networking issue going on somewhere, he suggested I take it to Ford direct as networking issues can be really difficult to troubleshoot.

Any ideas what an injector for this car would cost new/refurbed (if possible) and an injector reocde?

for one injector, you could be looking at £80 - £200 depending on what you get your hands on (recon, through to new). Then coding would be about £50 - £80.

The other issues appear to be wiring related, sounds like you have either a bad harness, possible water ingress, or bad connections on the fuseboard / fuse box etc
