Automatic transmission self-diagnosis Toyota Camry
Note: This procedure applies to Camry models manufactured from 1995 to 2001.
Required tools:
* Paperclip or piece of wire
Steps:
1. Stop the car and put it in park.
2. Locate the diagnostic connector under the hood. It is usually located near the fuse box or battery.
3. Take a paperclip or piece of wire and insert it into the “TC” or “DLC” hole on the diagnostic connector. Hold it for 3 seconds.
4. Remove the paperclip or wire from the connector.
5. Start the engine.
6. A diagnostic code will be displayed on the instrument panel. It will flash in a sequence of long (1.5 seconds) and short (0.5 seconds) flashes.
7. Calculate the code by counting the number of long and short flashes. For example, a long flash followed by two short flashes corresponds to code 12.
8. Continue counting codes until code 00 is displayed, indicating the end of the diagnosis.
Decoding codes:
* 11 — Malfunction of the gear selector position sensor
* 12 — Shift solenoid fault 1-2
* 13 — Shift solenoid fault 2-3
* 14 — Shift solenoid fault 3-4
* 15 — Malfunction of the torque converter lock-up solenoid
* 16 — Pressure control solenoid malfunction
* 21 — Error in the transmission fluid temperature sensor circuit
* 22 — Vehicle speed sensor malfunction
* 23 — Malfunction of the output shaft speed sensor
* 41 — Low transmission fluid level
* 51 — Shift solenoid 1-2 circuit malfunction
* 52 — Shift solenoid 2-3 circuit malfunction
* 53 — Shift solenoid 3-4 circuit malfunction
* 54 — Torque converter lock-up solenoid circuit malfunction
* 55 — Pressure control solenoid circuit malfunction
* 71 — Transmission system malfunction
Important:
*If any fault code is displayed, contact a qualified mechanic for further diagnosis and repair.
* Do not repeat the self-diagnosis test too often, as this may drain the battery.
