Nissan Altima 2007-2012 Service Manual: P2135 TP sensor
Description
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 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 addition, 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 signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

3. Check the continuity between electric throttle control actuator harness connector and ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair open circuit.
4.CHECK THROTTLE POSITION SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between electric throttle control actuator harness connector and ground.
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK THROTTLE POSITION SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between electric throttle control actuator harness connector and ground.
2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK THROTTLE POSITION SENSOR
Refer to EC-436, "Component Inspection".
Is the inspection result normal? YES >> GO TO 8.
NO >> GO TO 7.
7.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
1. Replace electric throttle control actuator.
2. EC-436, "Special Repair Requirement" >> INSPECTION END
8.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK THROTTLE POSITION SENSOR
1. Turn ignition switch OFF.

Inspection
CHECKING CVT FLUID
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to
176°F). The fluid level check procedure
is as follows:
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
