P2135 TP SENSOR
P2135 TP SENSOR
DTC Description
INFOID:0000000010703053
DTC DETECTION LOGIC
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
DTC CONFIRMATION PROCEDURE
1.
CHECK DTC PRIORITY
If DTC P2135 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Is applicable DTC detected?
YES
>> Perform diagnosis of applicable. Refer to
NO
>> GO TO 2.
2.
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.
>> GO TO 3.
3.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Start engine and let it idle for 1 second.
2.
Check DTC.
Is DTC detected?
YES
>> Proceed to
ECM-364, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
.
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010703054
1.
CHECK DTC PRIORITY
DTC No.

DTC detecting condition
P2135
TP SENSOR-B1
(Throttle/pedal position sensor/switch “A”/
“B” voltage correlation)
Rationally incorrect voltage is sent to ECM compared with the signals from
TP sensor 1 and TP sensor 2.
Engine operating condition in fail-safe mode
Fail safe mode
Vehicle behavior
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 con-
dition. So, the acceleration will be poor.
NOTE:
If throttle position sensor1 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.
