P1741 CHERY. Gear selector rod motion sensor.
P1741 chery. Error description: gear selector sensor. Symptoms: 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. Analysis: short-circuit or short-circuit to power supply signal above 4.75V. 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. Solution: incorrect installation during assembly.
Step-by-step instructions for solving error P1741 CHERY, namely the replacement and correct installation of the sensor qr512e-1707015 gear selector rod, in case of leakage of seals on the rod, consists of the following items:
Item №1. Disconnect the cable (A) from the speed sensor qr512e-1707015, loosen the 2 screws (B), remove the sensor (C). During disconnection, the sensor will spring counterclockwise.
Item №3 Align the red mark on the groove of the axle (D) with the red mark on the position sensor qr512e-1707015 (groove on the axle with internal protrusion on the sensor), see photo below.
Item №4. Attach the sensor base, and after alignment, rotate the sensor along a straight axis (D) clockwise until it aligns with the mounting hole.
Item №5. Secure the motion sensor with two screws. Carry out adaptive gear changes three times, after adaptive training it is necessary to turn off the ignition for 10-20 seconds.
Caution during operation of the gear selector motion sensor.
During normal operation and maintenance of the hydraulic unit, it is forbidden to flush the selespeed with a high-pressure water jet to prevent excessive ingress of water into the sensor, which may damage or intermittently malfunction the flexible circuit inside the motion sensor. If the working fluid leaks through the gear selector sleeves, breakage is also inevitable.
