DTCP0705TRANSMISSION RANGE SENSOR CIRCUIT MALFUNCTION (PRNDL INPUT)
CIRCUIT DESCRIPTION
The park/neutral position switch goes on when the shift lever is in the N o\
r P shift position. If the shift lever
is moved from the N position to the D position, this signal is used for \
air±fuel ratio correction and for idle speed
control (estimated control), etc.

HINT:

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for deter\
mining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.

(a)Check that the vacuum hoses are connected correctly.
(b)Check that the vacuum hoses are not loose or disconnected.
(c)Check the vacuum hoses and tubes for clogs, cracks, holes, damage, or bl\
ockage.
