DTC Description

DTC DETECTION LOGIC

DTC		CONSULT screen terms(Trouble diagnosis content)	DTC detection condition
P2135	00	TP SENSOR-B1(Throttle/Pedal position sensor/switch "A" / "B" voltage correlation)	Diagnosis condition	Engine running at idle
			Signal (terminal)	TP sensor 1 signal and TP sensor 2 signal
			Threshold	Rationally incorrect voltage is sent to ECM compared with the signals from TP sensor 1 and TP sensor 2
			Diagnosis delay time	-

POSSIBLE CAUSE

Harness or connector (TP sensor 1 or 2 circuit is open or shorted.)
Electric throttle control actuator (TP sensor 1 or 2)

FAIL-SAFE

Engine operating condition in fail-safe mode
Fail safe mode		Vehicle behavior
Device fix mode		This mode fixes the EVT control solenoid valve in the reference position. The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
Others		The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. Therefore, the acceleration will be poor. NOTE: If accelerator pedal position sensor 1 and 2 malfunction at the same time conducts following control. ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring.

DTC CONFIRMATION PROCEDURE

CHECK DTC PRIORITY
If DTC P2135 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.

PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 8 V at idle.
