Exhaust pressure sensor

Post by Fantomino » Sun Nov 17, 2019 11:02 am

Hi everyone. I have a Nissan Pulsar 1.5 dci myself, great runner and all that. Not long ago I had this error code coming up P0471 and P0472 and apparently is the exhaust pressure sensor. Looked after it on Internet, I found the sensor but no chance to find it on the car. Anyone knows the location? Or another way to solve this? Thanks

It's behind the EGR.

I think you can reach it by removing windshield wiper, all plastic cowls, wiper motor and the metal under it. Probably you need to remove the air intake pipe too.
Does it throw a check engine too?

Hi. I took the car to the mechanic and changed the sensor. He also done a regeneration of the dpf. After 3 day with no error, I had the same problem. A massive headache to be honest. Any ideas why?

In the picture above, the two hoses (black and brown) dry out and crack.
I'm a nissan techy and this is very common, try and get your old sensor back as spare if possible and change those pipes.

Good luck :)

P.s, you can access them from below on a ramp. Bit of a struggle but better than all the stripping up top.
