Vehicle make/model = 1997 grand am
Mileage = 150000
Engine size = 4.2
dash lights = check oil light
codes = no
work done prior = none
work done to repair = changed the oil sending unit but did not help.so
when we start the engine back up the engine light will come back on
turn the engine off start back up and check oil light will not be on
tech = jk
question = pleaes read above
JK:
Could you please tell me engine size again, it is not a 4.2l.
And are you referring to oil pressure sensor, or oil level, thanks

JK:
OK. Check oil pressure to be sure it is not an oil pressure problem, but it does not sound
like it. 1 of 3 things possibly wrong here. An intermittent open in the indicator input wire to
the pcm from the sender, brn wire terminal B at sender. A faulty pcm. Or a faulty cluster.
The pcm sees the input from the sender, and sends a signal to cluster on the serial data
line. The cluster logic deciphers all the data on the serial data line to determine which
light to light. Most likely cause is a problem in the dash cluster.
