AT1–52 AT340E (2JZ–GE) AUTOMATIC TRANSMISSION – TROUBLESHOOTING DIAGNOSTIC TROUBLE CODE CHART If a diagnostic trouble code is displayed during the diagnostic trouble code check, check the circuit listed for that code in the table below and proceed to the page given. DTC No. | Blinking Pattern | Circuit | Diagnostic Trouble Code Detection Condition 38 | [blinking pattern] | A/T fluid temp. sensor | Either (a) or (b) are detected for 0.5 sec. or more. (a) Temperature sensor resistance less than 79 Ω (b) After the engine has been operating for 15 minutes or more, the resistance at the temperature sensor is more than 156 kΩ GE2919 42 | [blinking pattern] | No. 1 vehicle speed sensor | All conditions below are detected 500 times or more continuously. (2 trip detection logic) *3 (a) No No. 1 vehicle speed sensor signal in 16 pulses of No. 2 vehicle speed sensor signal. (b) Vehicle speed: 9 km/h (5.6 mph) or more for 4 secs. or more. (c) Park/neutral position switch: OFF (Other than P or N position) BE3934 61 | [blinking pattern] | No. 2 vehicle speed sensor | All conditions below are detected 500 times or more continuously. (2 trip detection logic) *3 (a) No No. 2 vehicle speed sensor signal in 4 pulses of No. 1 vehicle speed sensor signal. (b) Vehicle speed: 9 km/h (5.6 mph) or more for 4 secs. or more. (c) Park/neutral position switch: OFF (Other than P or N position) BE3935 62 | [blinking pattern] | No. 1 solenoid valve | (1) Solenoid resistance of 8 Ω or less is detected (*) 8 times or more when No. 1 solenoid is energized. (2) Solenoid resistance of 100 kΩ or more is detected (*) 8 times or more when No. 1 solenoid is not energized. (*) If the above failures are detected less than 8 times, the ECM memorizes the malfunction code but the O/D OFF indicator light does not blink. BE3936 63 | [blinking pattern] | No. 2 solenoid valve | (1) Solenoid resistance of 8 Ω or less is detected (*) 8 times or more when No. 2 solenoid is energized. (2) Solenoid resistance of 100 kΩ or more is detected (*) 8 times or more when No. 2 solenoid is not energized. (*) If the above failures are detected less than 8 times, the ECM memorizes the malfunction code but the O/D OFF indicator light does not blink. BE3936 64 | [blinking pattern] | Lock–up solenoid valve | (a) Solenoid resistance is 8 Ω or lower (short circuit) when solenoid energized. (b) Solenoid resistance is 100 kΩ or higher (open circuit) when solenoid is not energized. (*) ECM memorizes diag. trouble code 64 if above (a) or (b) condition is detected once or more, but ECM does not start O/D OFF indicator light blinking. BE3934
