Honda Element. Manual — part 52

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.

DTC P0843 (25): ADVANCED DIAGNOSTICS

DTC P0843: OPEN IN 2ND CLUTCH TRANSMISSION FLUID PRESSURE SWITCH CIRCUIT, OR

General Description

The 2nd clutch transmission fluid pressure switch is installed in the hydraulic pressure circuit to the 2nd clutch.
When hydraulic pressure is supplied to the 2nd clutch, the switch is turned ON. When hydraulic pressure is not
supplied to the 2nd clutch, the switch is turned OFF. The signal of the 2nd clutch transmission fluid pressure
switch is input to the powertrain control module (PCM). The PCM detects the hydraulic pressure supply
conditions at the gear change to 2nd gear (1st --> 2nd, 3rd --> 2nd) to reduce the shock that occurs at the gear
change. If the 2nd clutch transmission fluid pressure switch is OFF while driving with the rotation speed ratio of
the input/output pulses in 2nd gear, the PCM detects a malfunction in the 2nd clutch transmission fluid pressure
switch and stores a DTC.

Malfunction Threshold

The input signal from the 2nd clutch transmission fluid pressure switch to the PCM is high when driving in 2nd
gear.

Driving Pattern

Start the engine, and drive the vehicle in D position and 2nd gear for at least 2 seconds.



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

General Description

The 3rd clutch transmission fluid pressure switch is installed in the hydraulic pressure circuit to the 3rd clutch.
When hydraulic pressure is supplied to the 3rd clutch, the switch is turned ON. When hydraulic pressure is not
supplied to the 3rd clutch, the switch is turned OFF. The signal of the 3rd clutch transmission fluid pressure
switch is input to the powertrain control module (PCM). The PCM detects the hydraulic pressure supply
conditions at the gear change to 3rd gear (2nd --> 3rd, 4th --> 3rd) to reduce the shock that occurs at the gear
change.

If the 3rd clutch transmission fluid pressure switch is ON while driving the vehicle with the speed ratio of the
countershaft to mainshaft in other than 3rd gear (the ratio is Neutral or 4th), the PCM detects a 3rd clutch
transmission fluid pressure switch failure and a DTC is stored.
