When the shift lever position is Neutral, pa
rk/neutral position (PNP) switch is ON. (M/T)
When the shift lever position is P or N, transmission range switch is ON. (A/T)
ECM detects the position because the conti nuity of the line (the ON signal) exists.

If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be su re to replace the coolant. Refer to CO-12, "
Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-8, "Draining" and LU-8, "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-15, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE

WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
DTC No. Trouble diagnosis name DTC detecting conditionPossible cause
P1217 Engine over temperature
(Overheat) • Cooling fan does not operate properly (Over-
heat).
• Cooling fan system does not operate properly (Overheat).
• Engine coolant was not added to the system using the proper filling method.
• Engine coolant is not within the specified range. • Harness or connectors
(The cooling fan circuit is open or
shorted.)
