Coolant Temp Sensor

[bubba]

Interesting, I have a couple of spare blue sensors at home.. when I get the 32 up and running I will swap a blue one in and see if it reads any differently.

My car also has the same issue as OP, when starting on cold start in mornings(stock ecu) the car will start to about 1krpm and then die if I do not blip the throttle for a split second. Something seems sticky... Its like something isn't opening up when it should be.

I don't really understand the logic behind the water temp sensor causing the issue... If it was f**ked, a rev will not fix it. My temp gauge is working just fine so that gets ruled out I guess.

When I get it tuned, ill get the tuner to check it over and clean any shit thats cleanable.

Interestingly enough though, back when I was running a power FC it never did this. Always started perfectly. Going back to stock ecu(had stock, went pfc, now stock but going back to pfc soon), the problem came back.

Temp gauge and ECU don't use the same sensor.

[SargeRX8]

That is probably true. But I still don't understand how it could cause a startup issue but be resolved with just the blip of the throttle.

[bubba]

Probably? it is definitely true.. there are two separate sensors, one for ECU and one for gauge.

Does it fix itself the instant you rev it? or are you giving it a few revs (and thus could be a time based thing)?

If the ECU temp sensor is fkd, after a short while the ECU will just assume the engine is up to temp and normal driving can ensue.

OP: is your R33 a Series 1.5 or Series 2? I have a red coolant temp sensor as well my part number on the sensor is....

A27-611

L00

This part number on the sensor does not seem to relate to any nissan part number in FAST but it does say JECS on the sensor and had the nissan symbol

regarding the RB26, does the intake temp sensor (the one at the front of the intake manifold) connect to the ecu? if so could this also contribute to crap cold/hot starts?

i know this is years old, but does anyone else know for sure whats an option to replace the cts sensor in an r33 gtst?

will this one work?

its says nearly every other nissan except gtst

also i am gonna ask the seller, just cant remember my login and password atm

i've got a r31 rb30 tridon sensor in my rb20, pretty much all the same thing long as its connected up the right way
