Fault diagnosis
ECU for a variety of sensors, actuators, and power
amplifier and detection circuits，To monitor when the
throttle position signal has a fault, the engine may not
have，If the method is started or the startup is diffi cult,
the common fault codes can be seen in the General
Table of Fault Codes.
Fault inspection of throttle position sensor and actuator:
◆ Check that the connector is well connected.
◆ Check whether the wire harness and sensor pins
are bent and deformed.
◆ Check the opening and breaking of all stitches (see
the defi nition of stitches in Figure A on the left).
◆ Check whether the supply voltage of pin 5 sensor is
5V.
◆ Check whether pin 1 voltage is 12V.
1. electronic throttle body connector on the motor PIN
between the (room temperature) resistance name
Mean value R = 1.4Ω±0.3.
2. Inductance L=1.1± 0.1MH3 at 1KHz ( room
temperature), working in the opposite direction the
allowable force on: < 200 N.
3. Maximum continuous power loss P = 8 W at ambient
temperature T=100°C，The maximum allowable
reversal current I is less than or equal to 10 A during
reversal.
4. Minimum working voltage: 8V
5. rated working voltage: 12V
6. overload working voltage: 17V
