Hello Fans
Easy question: How likely is for a knock sensor to fail on a 1990 A80Q 5cyl,
5sp, Calif car
with 130k miles?  I have my engine fault light coming on intermittently so,
after advice from
fellow fans, I cleaned and tightened (the already tight knock sensor) yet
left the wire
un-connected.  Now the engine light is not coming on, so maybe the sensor is
bad?  A caviat:
with connection to the sensor now removed, the low oil pressure light and
buzzer comes on
above ca. 2200 RPM. Is that normal?  How it is related to the knock sensor?

Any thoghts greatly appreciated,
Tony Ander.
