DTC P0732

Gear 2 incorrect (incorrect gear ratio detected)

DETECTION CONDITION

•  When all conditions below are satisfied with turn the ignition switch to the ON position (start engine).

Monitoring condition:

―  ATF temperature 20 °C {68 °F} or more

―  Driving in 2GR in D range

―  Engine speed 500 rpm or more

―  Turbine speed within 150—4,987 rpm

Diagnostic support note:

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.

•  The PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA is available.

•  The O/D OFF indicator light illuminates.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  ATF level low

•  Deteriorated ATF

•  Shift solenoid A, B stuck

•  Pressure control solenoid stuck

•  Line pressure low

•  2-4 brake band slipping

•  Forward clutch slipping

•  1-2 shift valve stuck

•  3-4 shift valve stuck

•  Pressure regulator valve stuck

•  Pressure modifier valve stuck

•  Solenoid reducing valve stuck

•  Control valve stuck

•  Oil pump malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information.
2		No	Go to the next step.
3	INSPECT ATF CONDITION • Inspect the ATF condition. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[GF4AX-EL].) ― Clear red: Normal ― Milky: Water mixed in fluid ― Reddish brown: Deteriorated ATF • Is it normal?	Yes	Go to the next step.
3		No	If the ATF color is milky or reddish brown, replace ATF, then go to Step 9
4	INSPECT ATF LEVEL • Start the engine. • Warm up the transaxle. • Is the ATF level within the specification? (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[GF4AX-EL].)	Yes	Go to the next step.
4		No	Add ATF to the specified level, then go to Step 9.
5	INSPECTION SHIFT SOLENOID VALVE A AND B FOR CLICK SOUND • Perform operation inspection. (See SOLENOID VALVE INSPECTION[GF4AX-EL].) • Verify the click sound of shift solenoid A and B when applying B+ to each transaxle terminal. • Was a click heard from solenoids?	Yes	Go to the next step.
5		No	Replace the solenoid that you could not hear a click sound, then go to Step 9. (See SOLENOID VALVE REMOVAL/INSTALLATION[GF4AX-EL].)
6	INSPECT LINE PRESSURE • Start the engine. • Measure the line pressures. (See MECHANICAL SYSTEM TEST[GF4AX-EL].) • Are the line pressures within the specifications?	Yes	Go to the next step.
6		No	• All ranges: Replace the oil pump or control valve body, then go to Step 9. (See CONTROL VALVE BODY REMOVAL/INSTALLATION[GF4AX-EL].) (See ATX Workshop Manual GF4AX-EL) • Any ranges: Replace or overhaul the automatic transaxle, then go to Step 9. (See AUTOMATIC TRANSAXLE AND TRANSFER REMOVAL/INSTALLATION[GF4AX-EL].) (See ATX Workshop Manual GF4AX-EL)
7	INSPECT STALL SPEED • Measure the stall speed in D range. (See MECHANICAL SYSTEM TEST[GF4AX-EL].) • Is the stall speed within the specification?	Yes	Go to the next step.
7		No	Replace or overhaul the automatic transaxle, then go to Step 9. (See AUTOMATIC TRANSAXLE AND TRANSFER REMOVAL/INSTALLATION[GF4AX-EL].) (See ATX Workshop Manual GF4AX-EL)
8	INSPECT FREQUENCY OF INPUT/TURBINE SPEED SENSOR WHEN DRIVING VEHICLE • Turn the ignition switch to the LOCK position. • Connect the M-MDS. • Start the engine. • Measure the frequency of input/turbine speed sensor while driving vehicle under the following conditions: ― Vehicle speed (VSS PID): 35 km/h {22 mph} ― Drive in the D range, 2GR ― Accelerator opening angle (APP PID): approx. 25% • Was the turbine speed at approx. 2,000 rpm?	Yes	Go to the next step.
8		No	Replace or overhaul the control valve body, then go to the next step. (See CONTROL VALVE BODY REMOVAL/INSTALLATION[GF4AX-EL].)
9	VERIFY TROUBLESHOOTING OF DTC P0732 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Start the engine. • Warm up the transaxle. • Drive the vehicle under the following conditions at least 4 times for more than 1.5 s: ― ATF temperature: 20 °C {68 °F} or more ― Drive in the D range, 2GR ― Accelerator opening angle (APP PID): 3.13% or more ― Vehicle speed (VSS PID): 9 km/h {6 mph} or more • Are any DTCs present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[L3].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[GF4AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[GF4AX-EL].)
10		No	DTC troubleshooting completed.
