Technical Details and Features

This Dorman throttle body (part number 977-814) features a 2.95-inch bore diameter and inlet/outlet size, optimized for gas fuel injection systems. The unit is constructed from aluminum and PBT materials, offering a balance of strength and lightweight design.

This throttle body is electronic and non-adjustable, designed to meet OEM specifications for Nissan Maxima models.

Applications and Problem Resolution

This throttle body is intended for use in Nissan Maxima vehicles experiencing issues related to throttle control and fuel delivery. It can help address:

  • Erratic or unresponsive throttle behavior
  • Engine stalling or rough idling due to faulty throttle position sensor
  • Reduced engine performance caused by air intake inconsistencies
  • Check engine light triggered by throttle body faults
  • Fuel injection system inefficiencies affecting acceleration

Installation Notes and Tips

Installation of the Dorman 977-814 throttle body requires removal of the existing throttle body unit. Note that mounting hardware and gaskets are not included and should be sourced separately. Ensure all electrical connections, including the six-pin male connector, are securely attached. It is recommended to inspect and clean the throttle body mounting surface before installation to ensure proper sealing and fitment. Calibration or relearning procedures may be necessary after installation to optimize throttle response.
