P2135 TP SENSOR
Component Description
INFOID:0000000005273394
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addi-
tion, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condi-
tion.
On Board Diagnosis Logic
INFOID:0000000005273395
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MIL lights up.
DTC Confirmation Procedure
INFOID:0000000005273396
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 8V at idle.
WITH CONSULT-III
1.
Start engine and let it idle for 1 second.
2.
Check DTC.
3.
If DTC is detected, go to
.
WITH GST
Follow the procedure “WITH CONSULT-III” above.
Diagnosis Procedure
INFOID:0000000005273397
1.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.

Throttle position sensor cir-
cuit range/performance
problem
Rationally incorrect voltage is sent to ECM
compared with the signals from TP sensor 1
and TP sensor 2.
• Harness or connector
(The TP sensor 1 and 2 circuit is open or
shorted.)
(APP sensor 2 circuit is shorted.)
• Electric throttle control actuator
(TP sensor 1 and 2)
• Accelerator pedal position sensor
(APP sensor 2)
Engine operation condition in fail-safe mode
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.
So, the acceleration will be poor.
