Error Code P1126 is defined as Throttle Control Motor Relay Circuit Open. This means the voltage power source for throttle control is excessively low, which could be a case of leak in the seal or the thermostat is stuck open.
What is a throttle control motor relay?
The throttle control motor relay on a 2000 Nissan Maxima is designed to regulate power to the throttle control motor. The engine control module (ECM) activates the relay in order to open and close the throttle control motor, which allows air in and out of the throttle body to control the engine idle speed.
What is code p1121?
Anything that has to do with emissions illuminates the “check engine” light; if something goes wrong with this valve, the “check engine” light comes on. …
Does the throttle body have a relay?
The power provided to the electronic throttle actuator is regulated by the actuator relay in the underhood fuse panel. It acts as a switch, sending power to the throttle actuator when it is required.
What is a coolant flow control valve?
Coolant switch valves control the coolant flow in side-flow cooling circuits of the powertrain and in the heating circuits of passenger compartments. In hybrid and electric vehicles, they can be used for coolant flow distribution, e.g. for cooling the battery and power electronics.
Is there a fuse for electronic throttle control?
The power provided to the electronic throttle actuator is regulated by the actuator relay in the underhood fuse panel. If the electronic throttle actuator relay is not switching as it should, the Check Engine light will illuminate, and the throttle will not be responsive when the accelerator pedal is pressed.
How does accelerator pedal sensor work?
The APP sensor essentially tells your engine how fast or slow to drive as you press the gas pedal. When you press down or lift off the throttle, it sends an electrical signal to the vehicle’s ECU or ECM as it’s also referred to, and then transmits that signal to the fuel system.
What does an accelerator pedal position sensor do?
The accelerator pedal sensor transmits the position of the accelerator pedal to the engine control unit. Based on this information, the load requested by the driver can be implemented immediately.
What causes P1101?
Some of the possible causes of a P1101 trouble code include a faulty MAF sensor, faulty connectors or wiring within the MAF sensor harness, and an air leak either before or after the MAF sensor. A poor electrical connection within the MAF sensor circuit can also cause the storage of this code.
