Trouble code list of QQ AMT Transmission

1. Clutch Travel Sensor

P1741 short-circuit or short-circuit to power supply signal above 4.75V ON

Open-circuit or short-circuit to grounding wire signal less than 0.39V

Failure of parts or mechanic part failure of clutch speed, or the re-measurement of

clutch speed not equals to estimated speed.

Engine off, engine flameout, start failure and gearshift failure

Engine started, but incapable of upshifting to gear 2.

System auto settings can’t be started.

2. Gear Selector Travel Sensor

P1742 signal above limit value short-circuit or short-circuit to power supply

signal above 4.64V ON

Signal less than limit value open-circuit or short-circuit to grounding wire signal

less than 0.29V

Without effective signal failure of parts or mechanical part signal out of limit value

than 0.19v

Without effective signal circuit malfunction or out of dynamic scope electric signal

reception scope, but not verified between

the position indicator sensor and friction

plate speed signal.

System gearshift failure

In event of above malfunction, the vehicle speed should not exceed 4KM/H and the engine speed should not exceed

1,800RPM. Gear 1, gear 2 and reverse gear can be engaged, accelerator position is limited to below 45%, and the engine stop

and idling request are allowed.

signal above 4.88V ON

Signal less than limit value open-circuit or short-circuit to grounding wire

signal less than 0.24V

Without effective signal circuit malfunction sensor grounding wire not

connected

The pressure pump is activated at fixed time

System auto settings can’t be started.

System automatically enters into automatic mode

The brake pedal must be depressed at engine start

The system will automatically engage gear 1 while the brake pedal keeps depressed.

It’s not allowed to shift to reverse gear

7. Gearshift Lever Malfunction 2

P1748 signal above limit value short-circuit or short-circuit to power

supply signal above 4.5V ON

Signal less than limit value open-circuit or short-circuit to grounding wire

signal less than 0.5V

Without effective signal out of dynamic scope circuit malfunction

System automatically enters into automatic mode

The brake pedal must be depressed at engine start

The system will automatically engage gear 1 while the brake pedal keeps depressed.

It’s not allowed to shift to reverse gear

8. Gearshift Lever Malfunction 3

P1748 signal above limit value short-circuit or short-circuit to power

supply signal above 4.5V ON

Signal less than limit value open-circuit or short-circuit to grounding wire

signal less than 0.5V

Without effective signal out of dynamic scope circuit malfunction

System automatically enters into automatic mode

The brake pedal must be depressed at engine start

The system will automatically engage gear 1 while the brake pedal keeps depressed.

It’s not allowed to shift to reverse gear
