==Adjustment of Idle Position Switch and Throttle Position Sensor (TPS)==
It is alot and be sure to use a feeler guage otherwise it won't be right
#Disconnect the throttle position sensor connector.
#:[[Image:TPS1.jpg]]
#Using jumper wires, connect an ohmmeter across terminal
#:3 (idle position switch) and terminal 4 (sensor ground) ofthe throttle position sensor.
#:[[Image:TPS2.jpg]]
#:[[Image:TPSconnector.jpg]]
#Insert a 0.65-mm-thick feeler gauge between the fixed SAS and throttle lever.
#:[[Image:TPS3.jpg]]
#Loosen the throttle position sensor mounting bolts and turn the TPS body fully counterclockwise.
#:[[Image:TPS4.jpg]]
#In this condition, check that there is continuity across terminals 3 and 4.
#Slowly turn the throttle position sensor clockwise until you find a point at which there is no continuity across terminals 3 and 4. Then, tighten the throttle position sensor mounting bolt securely.
#:[[Image:TPS5.jpg]]
#Connect the throttle position sensor connector.
#When using the multi-use tester, connect it to the diagnosis connector.
#When not using the multi-use tester, proceed as follows:
#*Disconnect the throttle position sensor connectors and connect the special tool, Test Harness Set, between the disconnected connectors.
#*Connect a digital voltmeter between the throttle position sensor terminal 2 (sensor output) and teminal 4 (sensor ground).
#:[[Image:TPS6.jpg]]
#Turn the ignition switch ON (but do not start the engine).
#Check the throttle position sensor output voltage. When using the multi-use tester, select item No. 14 and read the throttle position sensor output voltage. Standard value: 400 - 1,000 mV
#If the voltage is out of specification, check the throttle position sensor and associated harnesses.
#Remove the feeler gauge.
#Turn the ignition switch OFF.

==Checking the Throttle Position Sensor==
It is a good idea to check the throttle position sensor to make sure it's functioning correctly.

#Disconnect the throttle position sensor connector
#:[[Image:TPScheck1.jpg]]
#Measure rsistance between terminal 4 (sensor Ground) and Terminal 1 (sensor power) Standard value 3.5 - 6.5 Kilo Ohms
#:[[Image:TPScheck2.jpg]]
#Connect a pointer type ohmmeter between terminal 4(sensor ground) and terminal 2 (sensor output).
#:[[Image:TPScheck3.jpg]]
#Operate the throttle valve slowly from the idle position to the full open position and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
#:[[Image:TPSWiring.jpg]] [[Image:TPScheck4.jpg]]
#If the resistance is out of specification, or fails to change smoothly, replace the throttle position position sensor. Torque to 2.0 Nm (1.5 ft.lbs.)

==Checking the Throttle Position Switch==
To check the throttle position switch in order to verify that it is functioning correctly:

The Idle postition switch is different from the sensor, The switch is only used to tell the ECU if the the car is at Idle or not.

#With the accelerator pedal released, check to be sure that the throttle valve lever or the fixed SAS is pushed, if not adjust the fixed SAS
#Disconnect the throttle sensor connector.
#:[[Image:TPSswitch3.jpg]]
#Check the continuity across the throttle position sneosr connector terminal 4 (sensor ground) and 3 (idle position switch)
