Only cel light. No oil light on. Car seems to run ok other than a bit of elevated rpms occasionally.
The teapot blipped (probably didn't notice since apparently it didn't stay on), and DTC was stored.
DTC P0524:00 Engine oil pressure too low
DETECTION
CONDITION
l The oil pressure switch is on for a continuous 5 s with the following condition met: (engine oil warning light illuminates
when 1 s has elapsed)
n When engine speed is above 650 rpm and engine coolant temperature is 30 C {86 F} or less
n When engine speed is above 1,500 rpm and engine coolant temperature is 68 C {154 F} or less
n When engine speed is above 2,500 rpm and engine coolant temperature is 68 C {154 F} or more
Diagnostic support note
l This is a continuous monitor (other).
l The check engine light does not illuminate.
l FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
l DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION Not applicable
POSSIBLE CAUSE
l Engine oil leakage
l Improper engine oil level
l Oil pressure switch connector or terminals malfunction
l Short to ground in wiring harness between oil pressure switch terminal A and PCM terminal 1P
l PCM connector or terminals malfunction
l Oil pressure switch malfunction
l Oil pump malfunction
l PCM malfunction

I guess technically it's possible to trigger it by exceeding certain RPMs with low coolant temp (i.e right after a cold start) for at least 5 seconds
