.

CIRCUIT OPERATION

• The input shaft speed sensor generates 0 ⇔ 5 

volts pulse signal when the input shaft rotates. 
The pulse signal frequency increases with a rise 
in input shaft speed.

• The input shaft speed sensor is connected to the 

PCM (terminals 64 and 88) via the input shaft 
speed sensor connector (terminals 1 and 2).

• The PCM detects the input shaft speed by the 

signal input to terminal 64.

• The input shaft speed sensor generates the pulse 

signal as the teeth of the reverse clutch retainer 
pass the magnetic tip of the sensor.

.

DTC SET CONDITIONS
If no output pulse is detected from the input shaft 
speed sensor for one second or more while driving in 
3rd or 4th gear at a speed of 30 km/h (19 mph) or 
more, it is judged that an open circuit or short circuit 
in the input shaft speed sensor circuit. If DTC 22 is 
set consecutively four times, the transmission is 
locked into 3rd gear or 2nd gear as a fail-safe mea-
sure, and the "N" range light flashes once per sec-
ond.

.

TROUBLESHOOTING HINTS (The most likely 
causes for this code to be set are:)

• Malfunction of the input shaft speed sensor circuit

• Malfunction of the reverse clutch retainer

• Damaged harness, connector

• Malfunction of the PCM

DIAGNOSIS

Required Special Tool:

• MB991502: Scan Tool (MUT-II)

STEP 1. Using scan tool MB991502, check data list item 22: 
Input Shaft Speed Sensor.

CAUTION

To prevent damage to scan tool MB991502, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Start the engine.
(3) Set scan tool MB991502 to data reading mode for item 22, 

Input Shaft Speed Sensor.

• When driving at constant speed of 50 km/h (31 mph), 

the display should be "1,400 

− 1,700 r/min". (Gear 

range: 4th gear)

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points 

− How to Cope with 

Intermittent Malfunction 

P.00-6

.

NO :  Go to Step 2.

STEP 2. Measure the power supply voltage at input shaft 
speed sensor connector C-16.
(1) Disconnect connector C-16 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 3 and ground.

• The voltage should measure battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 5.
NO :  Go to Step 3.
