Hi all, my range rover 4.0 thor p38,has just got back from diagnostics,and came up with lambdas not reading at all. Readings were 0.0. Does anyone know what might cause this?
Thought the Later P38's had 4, pre & Post cat Lambdas (2 on each branch)...!!There are two pairs of Lambda sensors on Californian (US too?) spec cars, UK cars only have the (pre cat?) lambdas, a numpty who doesn't know what he's doing might look at the wrong Lambda readings - the unfitted pair still exist according to the Engine Management Software software and show up as dead lambdas on my generic OBDII reader.
Thor have only 2 if its a uk model,the us spec have 4, so i have been informed via the guys at landrover.still my truck is'nt working could bothe lambdas go at the same time?or is it worse than that.please help i'm stuck.:drama:
Had a quick look earlier,could'nt see any water or corrosion at the end where the lambdas plug into.could the ecu have failed? if so would a 4.6 one fit?
Does anyone know where the wires go and if there is any fuses to the lambdas?As my rangey is now really lacking power and need it for work.
