Resolved Question:

Hi, I have a 2008 Ford Focus 1.6L Econetic. I noticed some power loss on the motorway but it went away. The engine light came on and the error code was P142F Exhaust gas recirculation (EGR) sensor D - circuit intermittent/erratic Wiring, EGR sensor, ECM. I brought it to a Ford garage. They found nothing wrong and charged me €93 to reset the computer. The next day, I noticed power loss again and looked down to find the engine light on again. The power loss seems to be intermittent.

Hi there good evening to you and sorry for the delayed response
Ok the most common cause of this issue is corrosion internal of the EGR valve
These 1.6 tdci Varients are prone for minor water /moisture ingress over time into the EGR valve body
This is normally visually obvious when you dissconnect the EGR valve multiplug and inspect both the plug and more importantly the pins of the EGR valve the pins usally show signs of blue/green corrodion at the very bottom of the pin/s
In this case I would replace the EGR valve to resolve the issue
The new valves have better water prevention measures
It was suspected the cause was down to the position of the multiplug (vertical )
If you need anymore help or advice on this issue please let me know

Thanks. I'll take a look at this.

I'm going to look into this a bit more, but I'm at work at the moment.

Is this something a layperson could do? I have a standard toolbox and not afraid to get my hands dirty.

And can you give me a very rough estimate of how much this would cost for me to DIY it?

Also, if you know of any online guide with pictures, that would save me searching for it.

Thanks!

Hi there ,good morning to you
No worries
Ok this isn't that bad a job however the new valve should be programmed /reset using diagnostic equipment as it is fully electric
The EGR vakve is located at the passengers rear top of the engine are(
To fit the EGR vaIve I always remove the wipers /wiper arms and scuttle panels to gain proper access to the valve
The valve its self is only held on by 2x8 mm bolts and a snap clip for the EGR feed pipe
The only tricky part is lining up the gasket but if you stick it to new valve it's easier to line up m
The pictures we have on our site only shows the valve /-gasket 2xbolts and .clip
As once you have the wipers and scuttle panels removed it's straight forward
If you need anymore help or advice on this issue please let me know

I got as far as the EGR valve but I couldn't figure out how to disconnect the multiplug. Could you give me some advice on that? Can it be disconnected without taking out the EGR valve?

Also, how safe is it to keep driving the car while I'm trying to fix it myself? I read online to listen for a clicking after switching off the engine. I did that and I noticed there are 2 or 3 clicks when the engine turns off with about 2-3 seconds between each. They are regular and actually sound like something opening and closing so I'm guessing/hoping the valve is indeed opening and closing.

That said, I am still noticing sluggish acceleration on the motorway.

Given that Ford looked at it and didn't find a problem, IF the EGR is not at fault, what would be the next most likely cause of this error?

I have an ELM327 on order.

Here's a photo of my EGR multiplug:

Hi there good evening to you
Ok the multiplug should have a small tab on it to lift up and remove the multiplug upward
Some very early ones come with the wire on them (follow the wire to a multiplug join )
The clicking noise is a self cleaning process to clean any carbon/gunk off the internsl poppet EGR valve

I disconnected the multiplug and both the plug and socket look fine. No sign of corrosion.

Below is the output from Forscan. After saving the below, I reset the DTC P042F and the engine light cleared. I rechecked the DTC and P042F came back straight away although the engine light didn't come back on.
