ETC(Electronic Throttle Control Valve) is the device controlling amount of air to engine acccording to driver’s intension. Different from the existing mechanical throttle valve which is composed of accelerator pecal and connecting wire cable, ETC consists of a motor, a throttle body and a throttle position sensor. Receiving input signals from electronic accelerator pedal module, PCM lets ETC motor control throttle valve. With ETC, cruise control system works without any additional device.
If PCM recognizes vehicle state as forced idle under detecting condition, it sets P2104 and MIL(Malfunction Indication Lamp) turns on.
Item | Detecting Condition | Possible cause |
DTC Strategy | ● This code detects if the system is in Forced Idle Mode | ● Faulty APS ● Faulty APS+Brake ● Faulty APS + Vehicle speed sensor ● Faulty APS + Vehicle speed sensor + Brake ● Faulty ETC Items(TPS or ETC motor etc) ● Faulty PCM |
Enable Conditions | ● Ignition "ON" | |
Threshold value | ● Forced Idle Mode is active | |
Diagnosis Time | - | |
MIL On Condition | ● 1 Driving Cycle |
[Tip 1]
- If P2104 and P1295 occur at the same time, first check APS and ETC items(TPS or ETC motor etc).
