Xe Matiz thì em không rõ nó thế nào, xe Escape thì cái bù ga (van không tải) nó thế này:
Cảm biến ga thì là 1 cục nhựa đen to = ngón chân cái, cũng có giắc cắm ra !!!
Để kiểm tra xe Matiz thì bác thử vào chỗ này xem sao.

Trước khi kiểm tra thì xem cái này:DTC P0505 Idle Air Control Valve (IACV) Circuit Fault
Switch the ignition OFF.
Remove the IAC valve connector.
Measure and note the resistance between terminal C and D of the IAC valve.
Now measure and note the resistance between terminal B and A of the IAC valve
Do you see that the value of the resistance is within the specified value? (40-80 ohms)
Diagnostic Tools
Probe the IAC valve electrical connection for proper mating.
Examine the wiring harness for damage.
See whether the throttle stop screw shows signs of distortion.
Also inspect the throttle linkage for signs of binding or excessive wear and tear.
The following conditions may be created by a slow or unsteady idle:
1) Fuel system very high or low.
2) Foreign material in the throttle body or in the induction system bore
3) A leaking or restricted intake manifold.
4) Excessive engine overloading. Check for seized pulleys, pumps, or motors on the accessory drive
5) Excess engine oil.
