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

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.
