Toyota Sienna Service Manual: Diagnostic trouble code chart
If a DTC is displayed during the DTC check, check the parts listed in the table below and proceed to the page given.
HINT:
- *1: Comes on MIL (Malfunction Indicator Lamp) light up
- *2: "DTC stored" mark means ECM memorizes the malfunction code if the ECM detects the DTC detection condition.
- This DTC may be output when the clutch, brake and gear components etc. inside the automatic transmission are damaged.

Transmission Range Sensor Circuit Malfunction
(PRNDL Input)
DESCRIPTION
The park/neutral position switch detects the shift lever position and sends
signals to the ECM.
MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position ...

VSC Warning Light does not Come ON
DESCRIPTION
The skid control ECU is connected to the combination meter via CAN and
multiplex communications.
If the skid control ECU stores DTCs to shut down TRAC and VSC operation, the VSC
warning light comes
on in the combination meter.

Brake Switch "A" Circuit
DTC P0571 Brake Switch "A" Circuit
DESCRIPTION
When the brake pedal is depressed, the stop light switch sends a signal to
the ECM. When the ECM
receives this signal, it cancels the cruise control. The fail-safe function
operates to enable normal driving
even if there is a malfuncti ...
Air Mix Damper Control Servo Motor Circuit (Passenger Side)
DESCRIPTION
The air mix control servo motor (air mix damper servo sub-assembly) is
controlled by the A/C amplifier.
The air mix control servo motor moves the air mix damper by rotating (normal,
reverse) with electrical
power from the A/C amplifier.
This adjusts the mix ratio of the air t ...
