Fig. 139: A/T Clutch Pressure Control Solenoid Valves Circuit Diagram

Fig. 140: Shift Solenoid Valve Output (D Position)

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 and countershaft revolutions. If a difference between the actual ratio and the commanded gear occurs
when shifting to each gear position, a malfunction in A/T clutch pressure control solenoid valve C or the
hydraulic system is detected and a DTC is stored.

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 P0842 (25): ADVANCED DIAGNOSTICS

DTC P0842: SHORT IN 2ND CLUTCH TRANSMISSION FLUID PRESSURE SWITCH CIRCUIT, OR
2ND CLUTCH TRANSMISSION FLUID PRESSURE SWITCH (CLUTCH) STUCK ON

Fig. 142: Gear Position Versus Shift Status Graph

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 ON while driving the vehicle with the speed ratio of the
countershaft to mainshaft other than 2nd (the ratio is Neutral or 4th), the PCM detects a 2nd clutch transmission
fluid pressure switch failure and a DTC is stored.

MONITOR DESCRIPTION

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

The input signal from the 2nd clutch transmission fluid pressure switch to the PCM is low when driving in 4th
gear.

Driving Pattern

Start the engine, and drive the vehicle in D position and 4th gear for at least 2 seconds.



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