General Description

2007 Honda Element EX

2007 ENGINE PERFORMANCE Advanced Diagnostics - Element

Shift solenoid valve C is installed in the transmission housing. It is controlled by the ON/OFF signal from the
powertrain control module (PCM) to apply line pressure to shift valve C. The signal from the PCM is output to
apply clutch pressure control pressure to the proper gear change clutch according to the gear change schedule.
When the signal to shift solenoid valve C from the PCM is OFF, line pressure is discharged, and shift valve C is
inactive. When the signal to shift solenoid valve C from the PCM is ON, line pressure is applied to shift valve
C, and it operates against the shift valve C spring. The PCM monitors the mainshaft speed and the countershaft
speed at the gear change determined by the shift schedule. When an improper gear ratio is output compared to
the predetermined gear change mode, a shift solenoid valve C OFF failure is detected and a DTC is stored.

Driving Pattern

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.
