Question about 1991 Honda Accord
How do i solve the engine diagnostic code # 7 problem. stating throttle angle sensor- open or short ciuruit
First check for power and grounds at the sensor. Check for voltage at the signal wire, and continuity on the signal wire bt the sensor and the ecu. if all your circuits are OK then replace the sensor.

Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition
