Car broke down - ODB error codes 14 and 24

yoshi123 · 11-20-2011, 02:45 PM

Car about 2 weeks ago flicked up an engine light and wouldn't let me go past 2000rpms. Tried to get car to go past 2000rpm few times, then sat behind traffic for 5 minutes, car then ran as normal.

Drove car for further 2 weeks, no problems. Ran sweet as.

Then did a short run 3 miles. Stopped car, did shopping. Then drove back 1/2 mile engine light came on, all other lights came on also. Car stopped dead, power steering stopped working. Tried to re-start, but then cut revs to 0rpm and stalled, all lights on. Tried again after 5 mins, got it about 30 yards then stopped. Called the AA and let car sit for 1h 20mins. AA started car, drove fine for 1 mile. Then we drove back home, 3 miles. No problems.

Did the paperclip method diagnostic - pulled codes 14 and 24.

Code Description Causes
14 Ignition Signal Circuit
Open or short in IGF circuit from ignitor at ECU
Ignitor
ECU

Code Description Causes
24 Intake Air Temp Sensor Circuit
Open or short in intake air temp sensor circuit
intake air temp sensor
ECU

The car has a TOMS ECU and a MPH converter attached, stock twins, boost controller Blitz.

Should be worth noting I had a rad failure about 3 months ago, fluid all over the engine bay. I am not sure if this has had some effect, e.g.corroding some connector or something.

As far as I can see it's either intake Air temp sensor, Ignitor or ECU.

Ignitor symptoms seem to be car won't start - my car starts fine but randomly dies. Not sure if this is the issues.

My plan of action is to look is to trace the wires back to the ignitor (where is this btw?).

Otherwise, please help with some suggestions to fix.
