Toyota RAV4 Service Manual: Steering angle sensor circuit malfunction

Description
The steering sensor signal is sent to the skid control ecu via the can
communication system. When
there is a malfunction in the can communication system, it is detected by the
steering sensor zero point
malfunction diagnostic function.

Inspection procedure
Hint:
- When u0073/94, u0123/62, u0124/95 or u0126/63 is output together with
c1231/31, inspect and
repair the trouble areas indicated by u0073/94, u0123/62, u0124/95 or
u0126/63 first.
- When there are problems with the speed sensor or the yaw rate sensor,
dtcs for the steering sensor
may be output even when the steering sensor is normal. When dtcs for the
speed sensor or yaw rate
sensor are output together with other dtcs for the steering sensor, inspect
and repair the speed
sensor and yaw rate sensor first, and then inspect and repair the steering
sensor.
- Check harness and connector (momentary interruption)
- Using the data list of the intelligent tester, check for
any momentary interruptions in the wire harness and
connectors between the skid control ecu and the
steering sensor (see page bc-23).

Ok:
there are no momentary interruptions.
Hint:
Perform the above inspection before removing the
sensor and connector.

- Check dtc
- Clear the dtc (see page bc-47).
- Turn the ignition switch off
- Turn the ignition switch on again and check that no can
communication system dtc is output.
- Drive the vehicle and turn the steering wheel to the right
and left at a speed of 35 km/h (24 mph) and check that
no speed and yaw rate sensor dtcs are output.
Result 

- Check wire harness (steering sensor - battery and body ground)

- Remove the steering wheel assembly and the column
cover.
- Disconnect the e11 sensor connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Measure the resistance of the wire harness side
connector.
Standard resistance 

Replace steering sensor
- Repair or replace harness and connector (steering sensor to skid
control ecu)
- Reconfirm dtc
- Clear the dtc (see page bc-47).
- Start the engine.
- Drive the vehicle and turn the steering wheel to the right
and left at a speed of 45 km/h (28 mph) or more for
several seconds.
- Check if the same dtc is recorded (see page bc-47).

Description
This dtc is output when the vsc system detects a malfunction in the abs
system.
Inspection procedure
Check dtc for abs system
Clear the dtc (see page bc-47).

The skid control ecu receives signals from the yaw rate and deceleration
sensor via the can
communication system.
The yaw rate sensor has a built-in deceleration sensor and dete ...

Throttle / pedal position sensor / switch "A"
Hint:
These dtcs relate to the throttle position (tp) sensor.
Description
The tp sensor is mounted on the throttle body, and detects the opening angle
of the throttle valve. This
sensor is a non-contact type. It uses hall-effect elements in order to yield
accurate signals even in
extrem ...
Ambient air package
Concept
The Ambient Air Package can be used to clean
and scent the interior air with high-quality fragrances.
Ionization is used to clean the air from suspended
particles. Together with the selected fragrance,
ionization contributes to well-being and
relaxation while driving.
