L322 TDV8 MAP Sensors

colinb444 · Jan 20, 2024

Hello
Still trying to find the source of a PO23D error on my 2007 3.6 TDV8 l322.
When I bought the car the garage mentioned they were waiting for some new sensors.
I have pulled out the Map sensors and they looked brand new so assume these were the
sensors that have been replaced (probably trying to chase the fault).
Question is how do I know if these sensors are genuine Land Rover?
Had them out again and they are marked with HITACHI PS91 3T 1520.
Anyone know if these are Genuine Land Rover.

Thanks

They could be an alternative replacement

I'd be more concerned why they are replacing sensors when the plastic pipes are prone to splitting causing correlation faults between the sensors

And the inlet manifolds... Ask me how I know!

For the OP, have a read of my thread here: https://www.landyzone.co.uk/land-ro...eak-and-cracked-manifold.381697/#post-5419450. You'll find the pictures on about post #10. I've had two of these now and they've both had this issue, both have had cracked inlet manifolds. Get yourself a Q-Bond kit from Amazon and some brake cleaner, fix it, build it up and you'll be set.

Hello Blob
Thanks for the reply.
Checking the inlet manifolds was the first thing i did. Made my own smoke machine and did the soapy water
test but can't see anything obvious.
