DTC 94
DTC 94 Chart:
Transaxle Shift Solenoid Status:
CIRCUIT DESCRIPTION
This electrical device is used to control fluid flow acting on the 1-2 and 3-4 shift valve. The solenoid is a normally open exhaust valve that is used in conjunction with the "B" solenoid to allow four different shifting combinations. The solenoid is attached to the control valve body within the transaxle. Ignition voltage is supplied directly to the "A" solenoid. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path.
DTC 94 WILL SET WHEN
- No DTCs 21, 22, 24, 28 and 56.
- Transaxle pressure switch indicating transaxle in D1, D2, D3, or D4.
- Engine operating.
- Vehicle speed 7 mph or greater.
- Throttle position of 15.7 degrees or greater.
- Gear ratio between 1.54 and 1.71 for 2 seconds with first gear commanded.
- Gear ratio between 2.87 and 3.11 for 2 seconds with second gear commanded.
- Gear ratio between 0.67 and 0.71 for 2 seconds with fourth gear commanded.
ACTION TAKEN (PCM WILL DEFAULT TO)
- With a current DTC 94 set, the PCM will illuminate the Malfunction Indicator Lamp (MIL) (Service Engine Soon).
- The PCM allows only second gear when any forward gear is selected.
DTC 94 WILL CLEAR WHEN
The fault no longer exists and the ignition switch is cycled "OFF" and "ON."
DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. This test checks the electrical operation of the solenoid.
2. This test checks the power feed to the solenoid.
DIAGNOSTIC AIDS
This diagnostic test checks whenever the commanded gear is achieved by monitoring the known ratio.
