New Zealand 2007 Freelander 2 TD4 SE Auto Sumatra Black
Fuel Rail Pressure Sensor and Intake Temp Sensor

P0193-00 Fuel rail pressure sensor high input

Monitoring on Torque app, goes up to ~24k psi on full load, looks fine to me? But looking at replacing my sensor... normally my google skills are pretty good, but can't seen to find the part number online. Anyone can help out?

When replacing do i have to bleed pressure from the rail, or is it not charged when engine off?


Also mentioning this in case could be related somehow -

Intake Temp sensor also playing up. Ambient temp of 15deg. Some days on startup reads correct, some days -12degC, some days +40degC. When obviously reading wrong the temp increases and decreases with load on the engine, but obviously way out. Was looking to replace this sensor at same time.

Cheers

How are you with a multimeter?

Temperature sensors tend to be fairly simple but sensitive devices, they tend to either work or drift, working intermittently tends to be connection problems.

from the wiring diagram it's just a two wire device from the ecu so "easy" to fault find - bearing in mind LR went to the trouble of gold plating to ensure good connection.
