Bank Angle Sensor Signal Line Open Circuit Inspection

Turn the ignition switch OFF.

Check for continuity between the bank angle sensor	[1]
2P connector [1] and ECM 33P (Black) connector
[2] of the wire side.
Connection: Red/blue – Red/blue
TOOL:
Test probe	07ZAJ-RDJA110	R/Bu
Is there continuity?
YES	–GO TO STEP 4.
NO	–Open circuit in Red/blue wire

Bank Angle Sensor Inspection

Replace the bank angle sensor with a known good one (page 4-48).

Connect the bank angle sensor 2P connector and ECM 33P (Black) connector.

Erase the DTC’s (page 4-5).

Turn the ignition switch ON and engine stop switch " ".

Check if the MIL blinks.

Does the MIL blink 54 times?

 

YES – Replace the ECM with a known good one,

and recheck.

 

NO – Faulty original the bank angle sensor.

MIL CIRCUIT TROUBLESHOOTING

Before starting the inspection, check the speedometer power input line (page 20-6).

 

With The Ignition Switch ON, The MIL Does Not Come On

 

If the engine can be started but the MIL does not come on when the ignition switch is turned ON and engine stop switch " ", check as follows:

 

Turn the ignition switch OFF.

 

Disconnect the ECM 33P (Black) connector (page 4-50).

 

Ground the following terminal of the wire harness side ECM 33P (Black) connector [1] with a jumper wire [2].

CONNECTION: White/blue – Ground

 

TOOL:

 

Test probe 07ZAJ-RDJA110

 

Turn the ignition switch ON and engine stop switch " " the MIL should come on.

 

– If the MIL comes on, replace the ECM with a known good one and recheck the MIL indication.

 

– If the MIL does not come on, check for open circuit in the White/blue wire between the speedometer and ECM 33P (Black) connector.

 

If the wire is OK, replace the speedometer.

 

With The Ignition Switch ON, The MIL Does Not Go Off Within A Few Seconds (Engine starts)

 

Turn the ignition switch OFF.

 

Disconnect the ECM 33P (Black) connector (page 4-50).

 

Turn the ignition switch ON and engine stop switch " ".

 

– If the MIL comes on, check for short circuit in the White/blue wire between the speedometer and ECM.

 

If the White/blue wire is OK, replace the ECM with a known good one and recheck.

 

– If the MIL turns off, check the following.

 

Check the continuity between the ECM 33P (Black) connector [1] of the wire side and ground.

CONNECTION: Blue – Ground

 

STANDARD: No continuity

 

TOOL:

 

Test probe 07ZAJ-RDJA110

 

If there is continuity, check for short circuit in the Blue wire between the DLC and ECM.

 

If there is no continuity, replace the ECM with a known good one and recheck.

SENSOR UNIT

 

REMOVAL/INSTALLATION

 

Remove the left fuel tank shroud (page 2-4).
	[2]
Disconnect the sensor unit 5P connector [1].		[3]

Remove the torx screws [2] and sensor unit [3] from the throttle body.

 

 

[1]

 

Remove the O-ring [1].

 

Install a new O-ring to the throttle body properly.

If the O-ring is not installed properly, the idle air will leak and engine idle speed will be unstable.

 

Install the sensor unit [2] to the throttle body by aligning the following:

 

 

		Align
	[1]

 

– Clip of the TP sensor with the boss of the throttle valve

 

– IAT sensor of the sensor unit with the hole of the throttle body

 

 

Install and tighten the sensor unit torx screws [1] to the specified torque.

TORQUE: 3.4 N·m (0.3 kgf·m, 2.5 lbf·ft)

 

Connect the sensor unit 5P connector [2].

 

Install the left fuel tank shroud (page 2-4).

Perform the TP sensor reset procedure (page 4-45).

TP SENSOR RESET PROCEDURE

If the sensor unit is removed, reset the throttle valve fully closed position as following.

 

1. Erase the DTC (page 4-5).

 

2. Turn the ignition switch OFF.

 

3. Remove the dummy connector.

 

4. Short the DLC [1] using the special tool.

 

TOOL:

 

[2] SCS connector 070PZ-ZY30100

5. Disconnect the ECT sensor 3P connector [1].

 

Short the ECT sensor 3P connector terminals of the wire harness side with a jumper wire [2].
