HINT:
This DTC is output when either of the above detection patterns is met.
MONITOR DESCRIPTION
The ECM compares the actual gear ratio with the target gear ratio. When the actual gear ratio and target gear ratio are different, the ECM detects the malfunction, illuminates the MIL and stores this DTC.

PROCEDURE
1. |
CHECK DTC OUTPUT (IN ADDITION TO DTC P2820) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Powertrain > Engine and ECT > Trouble Codes(e) Read the DTCs using the Techstream.
HINT:
If any DTCs other than P2820 are output, perform troubleshooting for those DTCs first.
