P0715 CHERY. Clutch disc speed
P0715 chery. Error description: clutch plate speed sensor. Symptoms: gearshift is limited, only capable of upshifting to gear 2 to the most extent. Analysis: without effective signal intermitted signal, electromagnetic interference engine speed not equals to clutch plate speed. With external confirmation only at ECU-OFF. Without signal sensor not connected frication plate speed, output shaft speed exceed the limit value. Solution: replacement of cuffs and faulty sensor, ie repair of clutch drive qr512e-1707018ab.
Error P0715 of the automatic robotic gearbox, hereinafter RKPP, is manifested on Chery QQ cars with the following symptoms: it is impossible to shift gears, it is only possible to shift to first gear, second gear and reverse gear.
Step-by-step instructions for solving error P0715 CHERY consist of the following items:
Item 1. Use the scan tool in the erase code menu to remove the error and remove the key from the ignition switch for 15-20 seconds.
Item №2. Check the clutch position, the ignition on and the started car on the lounge: if the values are very different from the standard value, it means that the clutch disc is very worn and needs to be replaced. Adaptation and coupling point training shall be performed after repair work. If all of the above is normal, go to the next item.
Item №3. It is necessary to check up whether the speed sensor of a primary shaft has roughnesses if so: 1. It is necessary to replace bearings of shafts of a check point as,, an input shaft of a transmission is weakened by axial and radial beating; 2. Check transmission oil, if the oil contains pieces of iron and dirt, change the transmission oil; 3. Error P0715 occurs together with P1818 - disassemble the gearbox and check that the first, second and fifth gear synchronizers are in normal condition, replace defective parts if necessary. You also need to screw back the sensor qr512e-1703621 through a gasket with a thickness of 0.2 mm.
Item №4. Check the clutch actuator: clutch position sensor malfunction, if working fluid gets into the clutch position sensor, it will be defective and may be accompanied by errors P1810 and P0715, respectively. To do this, use the repair kit qr512e-1707018ab clutch actuator with inner tube, cuffs and clutch position sensor. In case of detached hummock, the repair kit qr512e-1707018ab of the clutch drive with cable, cuffs and clutch position sensor is used. Clean the cable plug on the clutch position sensor.
After repair it is necessary to carry out adaptation, or to pump hydraulic system RKPP CHERY QQ.
