Coolant temperature sensor?

[KKson]

All, Using the part number from the parts list on this forum I ordered a new CTS ERR2081. Part looks the same as original but the garage have today fitted it and the engine will not even start with this sensor in it. Either it's faulty or is not suitable.

I've rung Rimmers who say that ERR2081 is for the diesel Landrover and will give an incorrect reading but they don't stock the correct sensor. I'm going to speak to Neil at ML Performance tomorrow but anyone else had this issue with using the ERR2081 part number? Thanks.

Hi Keith, I was the one who added ERR2081 to the list and the 400SX is currently running with it and just passed the MoT on emissions too so it's deffo compatible. Extra bonus is that it's all brass nut unlike the plastic rubbish we are being fobbed off with.

Rimmer's would say it's for something else wouldn't they so they can charge extra for an "SDi" one.

I would say your new one is faulty probably, or else something else got disturbed when fitting it. For example brittle wiring in the ECU loom, or the plug isn't plugged in, or the terminals in it are fuackered.

They are very easy to test just stick an ohmmeter across the two terminals and you should see 300 ohms +/- 100 when cold. That's what you need for starting.

Thanks for the reply Adam - I'll get them to double check the resistance first thing, before I order a new one. If okay then wiring. They've already made a new section of loom to pick up the dissy to coil wiring as the old wiring was shot. It might be the same. I've got a full spare loom but that's on standby for the 390SE. Cheers.

Hi Keith...Have you checked the plug connector and wires also..Remember what happened with me...
I used this one for mine and is perfect...

Yep, pretty much the first thing I checked! Will double check resistance but think the new sensor might be duff as the old sensor at least allowed the engine to run. Cheers.

If the resistance looks OK at the sensor

Sensor resistance was completely open circuit so definitely a buggered brand new sensor. New one arrived today so we will fit that.
