MONITOR DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM.
If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and sets the DTC.
This monitor runs when the vehicle is driven at 12.4 mph (20 km/h) for over 20 seconds.

INSPECTION PROCEDURE
HINT:
1 READ VALUE OF INTELLIGENT TESTER (STARTER SIGNAL)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / STARTER SIG.
(d) Check the value displayed on the tester when the ignition switch is turned to the ON position and START position.
OK
2 INSPECT PARK/NEUTRAL POSITION SWITCH
(a) Inspect the Park/Neutral Position (PNP) switch.
(1) Disconnect the P1 PNP switch connector.
(2) Measure the resistance according to the value(s) in the table below.
Standard resistance
(3) Reconnect the PNP switch connector.
3 READ VALUE OF INTELLIGENT TESTER (STARTER SIGNAL)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / STARTER SIG.
(d) Check the value displayed on the tester when the ignition switch is turned to the ON position and the START position.
OK
4 INSPECT IGNITION SWITCH ASSEMBLY
(a) Disconnect the I15 ignition switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Reconnect the ignition switch connector.
5 READ VALUE OF INTELLIGENT TESTER (STARTER SIGNAL)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the tester on.
(c) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / STARTER SIG.
(d) Check the value displayed on the tester when the ignition switch is turned to the ON position and the START position.
OK

On-vehicle inspection
1. INSPECT THROTTLE BODY
(a) Listen to the throttle control motor operating sounds.
(1) Turn the ignition switch to the ON position.
(2) When pressing the accelerator pedal position
sensor lever, listen to the running motor. Make
sure that no friction noise comes from the
motor.
If fricti ...
Installation
1. Install speed sensor (nc sensor)
(a) Coat the O-ring with ATF.
(b) Install the speed sensor with the bolt.
Torque: 11 N*m (115 kgf*cm, 8 ft.*lbf)
HINT:
Make sure to install the same manufacturer's
sensor.
(c) Connect the speed sensor connector.
