DTC P250A:00 [PCM (WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))]

DESCRIPTION	Engine oil level signal: engine oil level sensor malfunction
DETECTION CONDITION	Determination conditions	• PCM receives abnormal signal from the engine oil level sensor.
	Preconditions	• Battery voltage: 10—16 V • The following DTC is not detected: ― Communication error between engine oil level sensor and PCM: U1100:00 • Low-G (XY) sensor (built-into SAS control module) signal is normal
	Drive cycle	• 1
	Self test type	• CMDTC self test
	Sensor used	• Engine oil level sensor • Engine oil level sensor internal temperature sensor • Low-G (XY) sensor (built-into SAS control module)
FAIL-SAFE FUNCTION	• Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT	• Illuminates master warning light. (without multi-information display) • The master warning indication is displayed on the multi-information display. (with multi-information display)
POSSIBLE CAUSE	• Excessive engine oil level (oil level exceeds measurable upper limit range of engine oil level sensor) ― Poor drainage during engine oil replacement ― Excessive engine oil resupplying ― Poor oil level adjustment ― Engine oil dilution Note • If a condition in which the engine oil temperature does not increase sufficiently is repeated, such as when driving short distances, the fuel does not vaporize, engine oil dilution continues, and then the oil level increases. • Engine oil level sensor malfunction ― Clogging of oil passage to engine oil level sensor detection area ― Engine oil level sensor internal application specific integrated circuit malfunction • Erratic signal to PCM ― Engine oil level sensor connector or terminals malfunction ― Short to ground in wiring harness between engine oil level sensor terminal C and PCM terminal 2Y ― Open circuit in wiring harness between engine oil level sensor terminal C and PCM terminal 2Y • PCM malfunction

• The PCM receives the signal from the engine oil level sensor and diagnoses the following malfunctions.

• The PCM performs diagnosis when each of the preconditions is met during a drive cycle. If any of the above malfunctions is detected, a malfunction is determined, DTCs are stored and the master warning indication and engine oil level warning indication are displayed on the multi-information display and the master warning light and engine oil level warning light are illuminated.

1. Start the engine and run it at idle.
