The 6 Most Common Check Engine Light Causes in Fords. 1. A Loose Gas Cap. It’s so simple, and yet it will definitely trip your Ford’s check engine light: a loose or damaged gas cap. Often, this is a result of a missing O-ring; this will need to be replaced. Happily, this is a much simpler repair than some other issues on this list. The site you gave is a bit odd, it lists the sensor number (A or 1338678), but the photo is the Assy, and their compatibility list stops at 2008 for the Focus. But it looks the right part, it seems from the number it is the right sensor, with the hose. Hi Guys, I have a 2008 Ford Focus 1.6 Diesel (Manual) Trouble started a while back , the car sometimes wouldn't start and sometimes it would , it was throwing an engine malfunction light in the middle (small flashing red light) and an alarm sound and the car wouldn't start. Anyway, driving down a dual carriageway earlier today. My engine has the warning siren go off and a message on my dash says "Engine Malfunction". I lost power in my engine, so I pull over and turn the engine off. After a minute, I start it again and it's all back to normal. The check engine light is on, but that's not unusual, and it seems to Garage suggests it could be £1000 to £1500 to replace, this is due to them saying it's around 8 hours labour, and if there is debris in the oil, they would want to change the oil, filter and clean the engine etc. This makes sense, and I've seen other things online suggest that it can be up to 12 hours labour.

Modules should never be replaced based only on a 'U' code. These codes do not always indicate a problem, and can be caused by normal diagnostic functions, carried out on the vehicle. ===END PCM DTC U1900-E3===. ===OBDII DTC U1900-C===. Code: U1900 - CAN communication bus fault.

Hi there , good evening to you Ok the most common issue we see is an internal short in the injector This pulls up a code eg cylinder 3 circuit fault If this fault is intermitent we sometimes swap the injector from cylinder 3 to cylinder 2 (them clear the fault code ) and monitor the situation to see if The fault code pulls up cylinder 2 the next time the fault arises As this conpletley rules
Ford Model: Focus. Ford Year: 2011. UK/Ireland Location: Surrey. Posted June 14, 2020. Hi. Just had the yellow warning light come on the dash and I have a very basic OBD11 reader that read the fault code P0400 EGR flow malfunction. Can anybody please tell me is this serious and is it an easy fix?
This time a message of "Transmission Malfunction Service Now" popped up. I had to limp home on the shoulder of a busy street at no more than 25-30 mph. Planning on towing it back to the dealership tomorrow and fight them to actually replace the TCM part in accordance to Extended Warranty 14M02. Reply Quote. L. YTf2fGO.
