P1254 and P0524 codes
Getting two(2) codes, P1254 and P0524, low oil pressure.
Oil gauge drops to near 0 then slowly climbs back to near
normal. Getting a lot of lifter/valve chatter. Last night the
check engine light came on, the ABS shut down and lost
complete power to the engine on the highway doing
75mph. Have a bad feeling it's the oil pump going out .
Want to try swapping out the oil pressure sensor first to
rule that out. But I am looking at what looks like two
pressure sensors just above the oil filter. One facing
forward, the other towards the passenger tire well. Does
the 2009 5.7 hemi actually have 2 sensors or is there only
one? Or do you think it is the oil pump going out? (178,000
miles) Was the shut down a warning signal for a failing oil
pump?
