Code P1226 2008 Nissan Sentra Description
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.
What are the Possible Causes of the DTC P1226 2008 Nissan Sentra?
- Faulty Electric throttle control actuator (TP sensor 2)
- Electric throttle control actuator (TP sensor 2) harness is open or shorted
- Electric throttle control actuator (TP sensor 2) circuit poor electrical connection
