Thread: FPR temp sensor electrical connector clip.

Do you mean the clip that is part of the cable connector the one you depress to remove the connector? If so they are not available separately. A complete connector is required, although it should stay on without the clip.
Cheers Scott

It's something like this Help/12 pcs. 3/8, 1/2 and 5/8 in. steel quick connect retaining clip 800-801 - Read Reviews on Help #800-801

Pretty sure Supercheap Auto and Repco keep similar clips in the blister packs. If I remember right it's a standard type connector like a smaller fuel injector connection so should be easy to match up.

The TD5's fuel temp sensor is ignored by the ecm in fuelling calculations although I don't recall if the ecu records a fault if the sensor circuit is open circuit. Try leaving the connector unplugged to see if it causes a fault when the ignition is switched on.

Sorry but i tend to differ, beside the description from RAVE i've seen a case with my own eyes when the engine ran bad cos there was a problem with the fuel cooler and the fuel temp reading was high... so i presume the ECM is using the signal for the addaptive strategy exactly as stated in RAVE

To achieve an adaptive strategy for acceleration the ECM uses input information from the CKP sensor, TP sensor,

implement the optimum fuelling strategy to facilitate acceleration.

^^^x2 agree with sierrafery , they didn't put the fuel temp sensor there just for a laugh, you can wire it in place temporarily

The fuel temp sensor shows as disabled in all ecu maps in Australian vehicles. Its possible that its used in colder climates.

Sierrafery, in which country did you experience the condition and why would you assume that poor running was because the temp sensor detected warmer than usual fuel? To me its an indication that the temp sensor was being ignored and therefore inadequate fuel was metered into the combustion chamber because the fuel was effectively diluted due to its higher than normal temperature.

Edit. Did you see a read-out of the fuel temp from the ecm?

Yes, the man complained about difficult hot start and rough running then i asked him to record a fuelling inputs log with nanocom and observed that the FT reading was the same with the ECT reading,... the problem was with the fuel cooler's thermostat which was blocked and bypassed the coolant from the cooler, after this was fixed the FT reading came back to normal(aprox 20*C lower than ECT) and the engine came back to it's normal behaviour
