Rebuilt Disco 4 Engine Issues

I'll be checking everything to do with the cam position sensor tomorrow. I'll post back with an update for you all.

Yep all references show one next to the LH EGR valve.

No show for a 2nd though..

the PO341 is common when the timing has been thrown out,

according to these guys..

that’s the D3 though , can happen also when the oil pump cover snaps causing the tensioner to come off, but alas op has rebuilt the engine with a new genuine oil pump cover, so should be ok

alas , one code can mean a multi tude of things , even worse with these D3/4

even a blown rear bulb or non can bus can sometimes give a list of fault codes u wouldn’t believe

fingers crossed it’s just a bad pin connection or maybe trapped / frayed etc on the cam sensor

If it’s of interest on a different sensor , the 2.7 has 1 x MAF sensor , 3.0 has x 2

plus I bet I’m going to have to eat the humble pie, again , lol

Could be anyting

indeed , ur spot on the there mate

Would hate to try and find faults on the top of the Range Rover models,

After many cut knuckles and time spent testing wires leading to no satisfactory conclusion, I managed to borrow a ridiculously expensive code reader which gave me a little more detail into the code. "P0341-3A Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or single sensor) - incorrect has too many pulses". How it can have too many pulses I don't know but I'll be picking up a new £156 cam position sensor tomorrow. Fingers crossed the car will burst into life once it's fitted...

Before fitting the new camshaft position sensor and after hours of looking at pictures taken during the rebuild, I noticed something that explained it all.. when setting the timing, I had the crankshaft locking tool in a hole on the flexplate for the torque converter, not the timing hole!! Annoyingly easily done since this particular hole is right next to the timing hole. Reassembled late last night after setting the correct timing, pushed the button and it burst into life instantly!! So pleased! Thank you all for the advice.

Great result.

Happy days

Good job !

happy days as I just saw what disco mikey mentioned ref the plates ( The flexplate only bolts on 1 way. There is 1 single offset bolt hole ) Said on the D3 forum

well chuffed for u and at least we know ref that plate and what fault it produces
