Honda Element. Manual - part 68

Malfunction Threshold 

The throttle valve is at a position greater than +5 ° from the fully closed position, or at a position lower than +3 
° from the fully closed position, for at least 2.5 seconds. 

Driving Pattern 

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator 

fan comes on.  

2. Turn off the ignition switch.  

3. Turn on the ignition switch.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
ECM/PCM memory. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs. 

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by 
disconnecting the battery.

General Description 

The electronic throttle control system controls the throttle valve opening. The system is composed of the throttle 
actuator, the throttle valve, throttle position (TP) sensors A and B, the throttle actuator control module, the 
throttle actuator control module relay, the accelerator pedal position (APP) sensor, and the engine control 
module (ECM)/powertrain control module (PCM). The throttle valve return spring is attached to the throttle 
valve gear to return the throttle valve to the default position. 

If the throttle valve does not return to the default position when the throttle actuator control module moves the 
throttle actuator to the default position from the middle position, a malfunction is detected and the malfunction 
data is transmitted to the ECM/PCM. When the ECM/PCM receives the malfunction data from the throttle 
actuator control module, the ECM/PCM detects a malfunction in the throttle valve return spring and a DTC is 
stored.

Fig. 200: Charging System Circuit Diagram 

General Description 

The alternator is driven by the engine, and it generates electricity to supply the necessary power to the electrical 
system and to charge the battery. The alternator voltage target values of 14.5 V and 12.5 V are achieved by 
switching the alternator control mode (controlled by the engine control module (ECM)/powertrain control 
module (PCM)). The alternator output signal is sent to the ECM/PCM, and it varies according to the battery's 
state of charge, the electrical load, and the engine speed.
