DTC P0841: Abnormality in Line Pressure Sensor Function

.

DIAGNOSTIC FUNCTION

TCM conducts fault detection by comparing the tar-

get line pressure reading with the actual secondary 

pressure reading.

.

DESCRIPTIONS OF MONITOR METHODS

The actual secondary pressure reading is 0.675 MPa 

(98 psi) or more, and the status over the target line 

pressure remains for 5 seconds.

.

MONITOR EXECUTION

• Transmission range: D

• Throttle valve opening : 1/8 or more

• Engine speed : 450 r/min or more

• CVT fluid temperature : from 20 to 180°C (68 to 

356

°F)

.

MONITOR EXECUTION CONDITIONS

Other Monitor (There is no temporary DTC stored 

in memory for the item monitored below)

.

DTC SET CONDITIONS

Check Conditions

• Transmission range switch position: D.

• Throttle position sensor voltage: 1.37 volts or 

more.

• Engine speed: 450 r/min or more.

• Transmission fluid temperature: 20°C (68°F) or 

more.

• Transmission fluid temperature: 180°C (356°F) or 

less.

• Voltage of battery: 9 volts or more.

• Voltage of battery: 16 volts or less.

JUDGMENT CRITERIA

• The actual secondary pressure reading is 0.675 

MPa (98 psi) or more, and the status over the tar-
get line pressure remains for 5 seconds.

.

OBD-II DRIVE CYCLE PATTERN

Transmission range: D (Drive the vehicle for 10 sec-
onds or more while the accelerator opening angle is 
20% or more)

.

PROBABLE CAUSES

• Abnormal line pressure

• Abnormality in secondary pressure sensor sys-

tem

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. Check other diagnostic trouble codes.
Q: Are other diagnostic trouble codes set?

YES : Go to the appropriate troubleshooting.
NO :  Go to Step 2.

STEP 2. Line pressure check
Carry out "hydraulic test" (Refer to 

P.23A-27

).

Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair according to the hydraulic pressure test 

diagnosis table.

STEP 3. Symptom recheck after erasing diagnostic trouble 
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Replace TCM.

DTC P0868: Secondary Pressure Drop

.

SECONDARY PRESSURE SENSOR 
SYSTEM CIRCUIT

 Refer to 

P.23A-81

.

.

DIAGNOSTIC FUNCTION

TCM detects the secondary pressure drop during 
driving.

.

DESCRIPTIONS OF MONITOR METHODS

• The value obtained by subtracting the actual sec-

ondary pressure sensor reading from the target 
secondary pressure sensor reading is 0.25 MPa 
(36 psi) or more.

.

MONITOR EXECUTION

• Engine speed : 450 r/min or more

.

DTC SET CONDITIONS

Check Conditions

• Engine speed: 450 r/min or more.

• Voltage of battery: 9 volts or more.

• Voltage of battery: 16 volts or less.

JUDGMENT CRITERIA

• Secondary linear solenoid performance fail [tar-

get secondary pressure 

− measured secondary 

pressure: 0.25 MPa (36 psi) or more. (1.5 sec-
onds)]: 2 count or more.

OBD-II DRIVE CYCLE PATTERN

Transmission range: D (Drive the vehicle for 10 sec-
onds or more while the accelerator opening angle is 
20% or more)

.

PROBABLE CAUSES

• Damaged wiring harness and connectors

• Malfunction of CVT assembly

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. Check other diagnostic trouble codes.
Q: Are other diagnostic trouble codes set?

YES : Go to the appropriate troubleshooting.
NO :  Go to Step 2.

STEP 2. Check the following connector:

• B-125 CVT assembly connector

• C-37 TCM connector

• A-12 Intermediate connector

Check contacts for internal short circuit.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair the defective connector.

STEP 3. Check for short to ground in the wiring harness 
between the TCM connector and the CVT assembly 
connector.

• Between C-37 TCM connector (terminal No.39) and B-125 

CVT assembly connector (terminal No.7)

OK: 100 

Ω or more

Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair the wiring harness.

STEP 4. Symptom recheck after erasing diagnostic trouble 
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Replace the TCM, and then go to Step 5.

STEP 5. Retest the system.
Q: Is the check result normal?

YES : The inspection is complete.
NO :  Replace the CVT assembly.
