Hi all,

After opening a thread on rangerovers.net where I got absolutely no replies whatsoever, I was advised to come here and talk to you about my P38's issues !

So let's hope I'm in the right place !

I noticed a very poor mileage, loss of performance and unburnt petrol (and its smell) spat out of the exhaust.

Hooked up the Torque android app, P0174 - Bank B too lean.

Yet my P38 is overfueling badly and therefore running extremely rich (trims at 25 on bank B, constantly enriching to the max).

I changed the 02's, nothing changed ...(they had about 70k miles on them so...couldn't hurt anyway)

I check the voltages, Bank A does vary between .1 and .9V, bank B stays fixed at 0.04-6V so very low...

I'm suspecting that it's a wiring issue.. shorted wire etc...

How can I test the wiring harness ?

Thanks a lot !

Vico
