FAIL-SAFE

When this DTC, as well as other DTCs relating to electronic throttle control system malfunctions is stored, the ECM enters fail-safe mode. During

fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 6锟斤拷 throttle angle by the return spring. The

ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing, in accordance with the accelerator

pedal opening angle, to allow the vehicle to continue running at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle

can be driven slowly. Fail-safe mode continues until a pass condition is detected, and the engine switch is then turned off.

WIRING DIAGRAM

INSPECTION PROCEDURE

HINT

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data

the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary,

if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Trouble Codes.

(e) Read the DTCs.

Result:

HINT

If any DTCs other than P2119 are output, troubleshoot those DTCs first.
