Honda Element. Manual - part 73

Start the engine, and accelerate the vehicle until the transmission shifts into 5th gear in D position.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM memory. If 
the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the freeze 
frame data are stored. 

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

General Description 

Hydraulic pressure to each clutch is controlled by the shift valve. The shift valve activates according to the 
ON/OFF status of shift solenoid valves A, B, C, D, and E. Hydraulic pressure supply in D position is shown

above. The line pressure or the clutch pressure control pressure (CPC A, CPC B, or CPC C) is supplied to each 
clutch by the shift valve activated. The powertrain control module (PCM) computes the actual ratio of 
mainshaft to countershaft revolutions. If a difference between the actual ratio and the commanded gear occurs 
when shifting to each gear position, a malfunction in the shift solenoid valve or the hydraulic system is detected 
and a DTC is stored.

DTC P2101: THROTTLE ACTUATOR SYSTEM MALFUNCTION 

Fig. 213: Throttle Actuator System - Communication Diagram 

General Description 

The electronic throttle control system (ETCS) 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
