Corsa B X12XE coolant temperature sensor hesitation
Posted: Sun Aug 23, 2009 6:33 pm
Hi,
Over the past few months, I have been indulging in my hobby of replacing each of the engine management system components in an attempt to track down a problem with my girlfriend's 2000 Corsa Sxi
However, I have almost come to the end of the list of things to try so I'm seeking help.
The car has a hesitation problem where at some point approx between 2 and 3k rpm, the power disappears and then comes back after a split second. All well and good unless you're trying to get out of a junction - not good. No lights appear when this happens.
To try and track down the problem the following have been tried:
Changed Coil pack
Changed Crank sensor (changed to fix another problem)
Changed Air flow meter
New Plugs and filters
Checked and WD40'd all connections and block connectors
The next (and last) thing on my list is the coolant temperature sensor. One thing I have noticed is that the middle copper core bit of this sensor, the bit that the spade connector goes onto, actually seems to spin round in the sensor body. Is this normal? I was just wondering could this be causing a loose connection. I can send a picture if need be.
Hope someone can help
Many thanks
Dan
