1998 Catera Cadillac.
Replaced air volume sensor.
Question = I have a 98 Caddy Catera and have been having issues with oil
pressure normally its borderline bad but today i had it drop into the red at a
stop sign.. So what i am wondering is would it be possible for it to just be a
bad ECT? The weird part is when its first started in the morning it is near 80
when accelerating until it gets warm. Now I'm stumped.. i was at first thinking
possibly a oil pressure sensor but when it got low the motor made some
noise so it def had low oil pressure. Do you think a engine coolant
temperature sensor could be the problem or is it something bigger? It might
have 2 ECT so not sure im guessing one to the pcm and one to the gauge
never goes past 3/4 and the fan does come on its just weird it got worse as
the weather got warmer.... Any ideas?
An engine coolant temperature sensor would not be the cause of this. If
the oil pressure is low, and the engine oil level was low, and there was
engine noise, i would say you have an internal oil pressure problem.
Going to have to get the oil pressure checked with a gauge.
Low pressure hot is usually a bearing problem.
