P167A-CALIBRATION MISMATCH

For a complete wiring diagram Refer to Section 8W.

Theory of Operation

During the initial ignition on, the Transmission Control Module (TCM) receives the calibrated data from the EEPROM
assembly inside the transmission and stores this information in the EEPROM of the TCM. At every ignition on, the
TCM compares the stored data in the EEPROM to the transmitted data from the EEPROM in the transmission. If
the calibration data does not match the DTC will set and the MIL will illuminate after one failure.

•

When Monitored:
One time at initial ignition on with a system voltage between 9.0 and 16.0 volts.

•

Set Condition:
If the TCM stored calibration does not match the EEPROM assembly in the transmission. This DTC requires
only one problem identification to set the MIL.

Possible Causes

TRANSMISSION CONTROL MODULE RELEARN PROCEDURE NOT PERFORMED

Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 —
TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT — STANDARD PROCEDURE)

Diagnostic Test

1.

PERFORM TCM RELEARN PROCEDURE

View repair

Repair

This is an informational DTC indicating that the TCM, CV Transmission, or the CV Transmission internal
controller (valve body) was replaced without being calibrated. With the scan tool perform a TCM relearn
procedure.

Perform CVT VERIFICATION TEST. (Refer to 21 — TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT —
STANDARD PROCEDURE)

P1702-PRIMARY OIL PRESSURE SENSOR / SECONDARY OIL PRESSURE SENSOR
CORRELATION

For a complete wiring diagram Refer to Section 8W.

Theory of Operation

The Transmission Control Module (TCM) monitors the correlation between the primary and secondary pressure sen-
sors. If the correlation between the sensors is out of range a DTC will set.

•

When Monitored:
Ignition on, system voltage between 9.0 and 16.0 volts.
Engine running with the transmission in Drive.
Vehicle speed greater than 10.0 Km/h (6.0 mph).
Accelerator Pedal Position (APP) greater than 12.5%.
Engine rpm greater than 450 rpm.
No active DTCs from the following:

•

Primary or Secondary Pressure Sensor

•

Transmission Temperature Sensor

•

TCC Lock Up Solenoid

•

Step Motor

•

Input or Output Speed Sensor

•

Transmission Range Sensor (TRS)

•

Line Pressure Solenoid

•

Secondary Pressure Solenoid

•

Set Condition:
Condition one:
Reported primary pressure is less than the lower limit of the primary pressure correlated with the reported
secondary pressure for more than 5.0 seconds.
Condition two:
Reported primary pressure is greater than the upper limit of the primary pressure correlated with the reported
secondary pressure for more than 5.0 seconds.

Possible Causes

PRIMARY PRESSURE SENSOR

SECONDARY PRESSURE SENSOR

TRANSMISSION CONTROL MODULE

Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 —
TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT — STANDARD PROCEDURE)

Diagnostic Test

1.

CHECK FOR TRANSMISSION DTC(s)

With the scan tool, read Transmission DTCs.

Are any of the following DTC(s) present PO842, PO843, PO847, or PO848?

Yes

>> Refer to the Transmission Diagnostic and Testing category and perform the appropriate symptom(s).

Perform CVT VERIFICATION TEST. (Refer to 21 — TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT —
STANDARD PROCEDURE)

No

>> Go To 2

2.

CHECK TO SEE IF THE DTC IS ACTIVE

With the scan tool, read Transmission DTCs.

Is the status Active for this DTC or is the STARTS SINCE SET counter 2 or less?

Yes

>> Go To 3

No

>> Go To 4

3.

CHECK THE TCM

Replace or repair (valve body) the CV Transmission per the Service Information. Perform CVT VERIFICATION
TEST. (Refer to 21 — TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT — STANDARD PROCEDURE)

Did the DTC reset during the verification test?

Yes

>> Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion,

damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for any
Service Bulletins for possible causes that may apply. If no problems are found, replace the TCM per the
Service Information.

Perform CVT VERIFICATION TEST. (Refer to 21 — TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT —
STANDARD PROCEDURE)

No

>> Test Complete.

4.

INTERMITTENT WIRING AND CONNECTORS

The conditions necessary to set this DTC are not present at this time.

Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

Wiggle the wires while checking for shorted and open circuits.

Were there any problems found?

Yes

>> Repair as necessary.

Perform CVT VERIFICATION TEST. (Refer to 21 — TRANSMISSION/TRANSAXLE/AUTOMATIC — CVT —
STANDARD PROCEDURE)

No

>> Test Complete.
