Where is the throttle control motor relay?
Locate the relay control box inside the engine compartment. It is a black plastic box on the left side of the engine compartment, between the power steering fluid reservoir and the fender.
How does the throttle control motor relay work?
The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery voltage is provided to the ECM.
Where does the power supply for the throttle control go?
The power supply for the throttle control provides the PCM (powertrain control module, also known as ECM or engine control module) through throttle control motor relay.
What is the throttle control motor relay on a Nissan Maxima?
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 to do when the throttle control motor fails?
When the throttle control motor fails, the engine may stall or have an erratic idle. Replacement relays are available from auto parts stores and Nissan dealers. Place the Maxima’s transmission in park (automatic) or first gear (manual). Shut off the engine, apply the parking brake and open the hood.
The power supply for the throttle control provides the PCM (powertrain control module, also known as ECM or engine control module) through throttle control motor relay.
The latter is turned On/Off by the former; when the ignition is switched off, the PCM will send a signal to the throttle control motor relay and a battery voltage is provided to the PCM. When the ignition is switched off, the PCM will send an off signal to the throttle control motor relay and battery voltage will NOT be provided by the PCM.

What is the error code for throttle control?
Table of Contents. 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.
