P1484 error code

Post by tyrellgovender14 » Thu Feb 11, 2021 7:18 pm

Hi All!

I've searched the forums and I'm coming up a bit short on this one. I have a 2014 J11 1.5 dci with 140k kms. Whilst driving long distance, the EML came on (orange) with the stop/start system fault constantly coming up. I also noticed the cruise control wouldn't stay activated anymore. The car still drove normally (75kms or so). The next morning, I started the car only to find erratic startup idle, and it wouldn't keep running unless you kept your foot on the accelerator. Once the car warmed up, it ran normally again. Had the codes read:

P1484 and P1496, searched them online but cannot get a consistent answer on what the codes mean.

Anyone else experience this fault or can help with the codes? Any guidance would be appreciated!

Tyrell

P1484 LOW PRESSURE EGR VOLUME CONTROL VALVE

P1496 is not mentioned in diesel engine diagnostics...is that number right?

Exhaust Gas control will cause problems with running and signal the EML light. Emissions story here:

Awesome! Thanks I'll give it a read and start looking there. I had some DPF issues recently, I'll have to check out all the EGR systems now.

Yep, P1496 is definitely the code coming up. The guy I had read the codes mentioned something about the 5V power supply being low or unreliable... Not sure how true this is. Hopefully if I can clear the EGR fault this will go away too.
