AT2–54 A340E (2JZ—GTE) 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 QD2919 A/T fluid temp. sensor Either (a) or (b) are detected for 0.5 sec. or more: (a) Temp. sensor resistance less than 79 (b) After the engine has been operating for 15 minutes or more, the resistance at the temp. sensor is more than 156 k . 42 BE3934 No.1 vehicle speed sensor All conditions below are detected for 4 secs. or more: (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 or more (c) Park/neutral position switch: OFF (Other than P or N position) 46 BE3934 No.4 solenoid valve All conditions below are detected for 1 sec. or more: (2 trip detection logic)*3 (a) ECM output duty signal to No.4 solenoid in 90% or higher duty ratio (b) Current to No.4 solenoid: 330±100 mA or less 61 BE3936 No.2 vehicle speed sensor All conditions below are detected: (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) 62 BE3836 No.1 solenoid valve (1) Solenoid resistance of 8 or less is detected (*) times or more when NO.1 solenoid is energized. (2) Solenoid resistance of 100 k or more is detected (*) 8 times or more when No.1 solenoid is not energized. (*) If the above failure are detected less than 8 times, the ECM memorizes the malfunction code but the O/D OFF indicator light does not blink. 63 BE3936 No.2 solenoid valve (1) Solenoid resistance of 8 or less is detected (*) times or more when NO.2 solenoid is energized. (2) Solenoid resistance of 100 k or more is detected (*) 8 times or more when No.2 solenoid is not energized. (*) If the above failure are detected less than 8 times, the ECM memorizes the malfunction code but the O/D OFF indicator light does not blink. 64 BE3936 No.3 solenoid circuit All conditions below are detected for 1 sec. or more: (2 trip detection logic)*3 (a) ECM output duty signal to No.3 solenoid in 90% or higher duty ratio (b) Current to No.3 solenoid: 450±100 mA or less
