Engine temp drop.

[mellts02]

Hi.

I have problem with my engine temp.
The thing is, as the engine reaches 79 degrees then for some reason it shows that temp starts to drop gradually and it goes all the way to -21.
I have tried three different sensors and they all do the same thing.
Its a SR20DE+T

Any ideas.

Thanks

Do you have a fault code? Perhaps measure the resistance of the sensor at the ECU plug

If you disconnect the sensor, what does the temperature show?

Problem solved.

The problem was those cheap no name 550 injectors i bought from Ebay few months ago.
Everything was working fine at first.
Runs good again with old injectors.
