P1217 ENGINE OVER TEMPERATURE

DTC Description

INFOID:0000000010986424

DTC DETECTION LOGIC

If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

CAUTION:

When a malfunction is indicated, be sure to replace the coolant. Refer to

CO-39, "Draining"

and

CO-40,

"Refilling"

. Also, replace the engine oil. Refer to

LU-26, "Draining"

and

LU-26, "Refilling"

.

1.

Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to

MA-24, "Engine Coolant Mixture Ratio"

.

2.

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

POSSIBLE CAUSE

• Harness or connectors (Cooling fan circuit is open or shorted.)
• IPDM E/R
• Cooling fan motor
• Radiator hose
• Radiator
• Radiator cap
• Reservoir tank
• Water pump
• Thermostat

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P1217 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or
P0607.

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to

EC-517, "DTC Index"

.

NO
