All the signs to coolant temp sensor faulty......but not quite?
Hi folks.
Need some advice here please.
The car struggles starting from cold and fan is constantly on and on computer showing high temp reading, even after warm and I switch engine off, still struggles to start.
But once started is fine.
Now I've replaced coolant temperature sensor with genuine part.
Took battery + off and removed alternator and fitted, put back together and still no difference.
Any advice where else to try? Or does battery need to be disconnected over night etc, as from disconnecting battery and connecting again was probably just under 1hr.
Car is a my99 with v7 block on a syvecs ecu.
Thanks in advance.

Me thinks it might be a syvecs problem as you seem to have done what i would have done firstly and you did change the coolant temp sensor and not the temp sender to the gauge.

Yes, this has gone in crossover pipe at front behind alternator v5 car with newage lump.

I've found a picture during my build and maker a circle round where/what I've replaced.
I've fitted it here,
With this sensor, notice it's a 3 wire and not a 2 wire which is v1-v4.

Mine has no sensors on back of crossover pipe. Notice they are blanked
V5 onwards are at the front and as you say do both hence why they are £40 instead of £15 for a 2 wire one.
So that to me says something to sort in map ecu settings.

Thought I might aswell update this seen as I forgot"
It was me not plugging the loom into the ecu pins correctly, unplugged and plugged back in correctly looool.
The pins must not have been all touching. Waste of a CTS for my stupidity.

I’m having similar issues.
Just having slightly opposite symptoms, SOMETIMES after my cars warm if I go into the store and come back out try to start, it barely starts with horrible bucking. Also showing code for 02 sensor bank 1 and running to lean bank 1. I swapped the o2 ($170) cleared the codes and It came back on sometime later. Someone referred this temp sensor, I’m driving a 03 Impreza outback sport with an 02 engine.
