No, opposite. I was following the debug procedure listed for my car on
alldata, to confirm the light worked. I wasn't having a problem with
the light or sensor, was just a 15 year old car and I was curious if
the sensor/light worked anymmore. Turned out the sensor was bad. The
float contact was rusted into the sensor and I could not get a
continuity reading between the two terminals.
In my case, a 1990 Escort GT, I think the circuit happened to be wired
such that if it failed it would just be left open. Bad sensor, no
effect on powering the light. Your sensor circuit might be wired to
"fail closed". Bad sensor, light's on. Just a guess.
But if that is the case a paper clip inserted into the connector
wrapped with some electrical tape should do the trick temporarily to
shut off the light. Worth a try at least.
Just an FYI, at this point in the life of your car you might start
running into assorted electrical problems (i.e., dirty contacts, rust,
corrosion, failed components) and some wiring diagrams will prove to be
extremely helpful. Suggest getting an alldatadiy account, best $25 I
ever spent on my old car.
