ecu code 1107? What does it mean?
I recently got an engine light and checked the codes. I got a KS code, and then 1103, 1105 and 1107. 1103 and 1105 are "improper shifting to first gear and third gear," respectively, but 1107 is undefined. 1106 is "improper shifting to fourth gear, " so I'm assuming that 1107 has something to do with the transmission. Anyone know what it might be?

1103 1104 1105 1106
Since DTCs 1103 to 1106 deal with the transmission, there is info on the 1106 DTC. Everywhere you see "4th gear", simply substitute "1st gear".
Diagnostic Trouble Code 1106 means "Automatic Transmission 4th gear malfunction."
This malfunction is detected when the automatic transmission does not shift into fourth gear or the torque converter clutch does not lock up as instructed by the Transmission Control Unit. The factory service manual lists these possible
causes...
- Shift solenoid A
- Shift solenoid B
- Overrun clutch solenoid valve
- Line pressure solenoid valve
- Each clutch
- Hydraulic control circuit
- Torque converter clutch solenoid valve
You can do some troubleshooting without opening the automatic transmission. Find the harnesses which emanate from the transaxle. One of them terminates in a brown plastic connector with eight pins. This is connector F42, located (approximately) above the transaxle case and below the black plastic engine air intake ductwork. With the engine off, disconnect F42. You want to measure the transmission side of F42. Hold the connector such that the plastic latch is at the top. You should now see two rows of four terminals. These are numbered (top row, left to right) 1 - 4, and (bottom row, left to right) 5 - 8. Make resistance measurements between a clean ground and the following terminals:
#1, Shift solenoid B, 20 - 40 ohms.
#2, Shift solenoid A, 20 - 40 ohms.
#3, Overrun clutch solenoid valve, 20 - 40 ohms.
#4, Line pressure solenoid valve, 2.5 - 5 ohms.
#5, Torque converter clutch solenoid valve, 10 - 20 ohms.
There is also a "bench test" procedure for testing these solenoids with a 12 volt supply such as a car battery. However, this requires removal of the shift solenoid valve assembly. I don't know if you want to get involved with that.
