P0732
Diagnostic Chart:
The transaxle control module (TCM) uses the transaxle input speed sensor (ISS) and transaxle output speed sensor (OSS) to determine input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio. The TCM uses this information to determine if the commanded gear matches the actual gear. DTC P0732 sets if 2nd gear is commanded and The TCM detects an actual gear ratio other than 2nd gear.
DTC PARAMETERS
DTC P0732 sets if 2nd gear is commanded and the TCM detects an actual gear ratio other than 2nd gear when:
^ Ignition voltage is at least 10.5 volts
^ Engine Speed is at least 400 RPM
^ Transaxle has been in a forward gear for at least 8 seconds
^ APP Angle is at least 10%
^ Transmission OSS is at ]east 500 RPM
^ Condition exists for 12 seconds
DTC P0732 diagnostic runs continuously when the above conditions have been met.
DTC P0732 is a type A DTC.
DIAGNOSTIC AIDS
IMPORTANT: If DTC P0717, P0722, P0963, P0973, P0974, P0976, P0977, P0979, P0980, P0982, or P0983 is set, diagnose that DTC first.
Observe Transmission ISS and Transmission OSS with a Scan tool. Compare with a known good vehicle to determine if the speed sensors are reading correctly.
Shift solenoid 2 may not produce any audible click noises when turned on or off. Shift solenoid 2 can not be tested by listening for audible click noises. Shift solenoid 2 may be stuck open if the vehicle has all of the following symptoms:
^ 2.22 Gear Ratio when 2nd gear
^ 1.45 Gear Ratio when in 3rd gear
^ 0.98 Gear Ratio when in 4th gear
Shift solenoid 1 produces an audible click noise when turned ON, but may not when turned OFF Do not replace shift solenoid 1 because it does not click OFF. Possible causes of incorrect 2nd gear ratio:
^ Shift solenoid 1 stuck closed
^ Shift solenoid 2 stuck open
^ Shift solenoid 3 stuck closed
^ Line pressure solenoid stuck closed
^ Valvebody
^ Forward Clutch (C1)
^ 1-2, reverse clutch (B5)
^ Inaccurate speed sensors
^ TCM
