How to Remove the Accelerator Pedal of Infiniti Q50L?
3 Answers
Electronic accelerator pedals are used in electronic throttle control systems. Their principle is to convert the throttle demand signal into a voltage signal through the pedal position sensor and send it to the ECU. The steps to remove the accelerator pedal of the Infiniti Q50L are as follows: 1. Prepare the tools for removal: flywheel wrench, pliers, flat-head screwdriver, etc. 2. Open the engine hood and remove the engine guard plate. 3. Use a flat-head screwdriver to pry open the small cover plate of the lower fixing screw of the accelerator pedal and remove the fixing screw. 4. Unplug the connector of the accelerator pedal, remove the accelerator pedal, and pay attention to the alignment hole after removal.
Removing the Infiniti Q50L's throttle pedal requires careful operation. Having handled similar models, I prioritize safety: disconnect the negative battery terminal to prevent electric shock, and wear gloves to avoid scratches. Next, remove the floor mats and carpets to expose the pedal area. The Q50L's pedal is typically electronic, so locate the mounting screws, usually requiring a 10mm wrench to loosen. After loosening, carefully unplug the wiring connector, avoiding forceful pulling to prevent pin damage. Finally, gently remove the pedal, being cautious not to damage the interior trim. Post-removal, I often clean dust or check for pedal linkage sticking. If springs show rust, applying lubricant can extend their lifespan. Take your time—rushing risks mistakes, especially during nighttime work where a flashlight is helpful. The process takes about 30 minutes, faster with experience, but beginners should consult manuals or videos first. During reinstallation, ensure proper alignment and tightness to prevent loosening while driving, which could affect control.
As a frequent DIY enthusiast, I emphasize safety first. Before removing the Q50L accelerator pedal, you must disconnect the battery and wait a few minutes to dissipate residual current to avoid electric shock. Then bend down to inspect the area beneath the pedal: some models require removing side panels, while the Q50L may need a small plastic cover to be pried open. There are usually two or three mounting screws, which can be removed with a Phillips screwdriver or socket wrench. The wiring connector often has a clip—press lightly to unlock before pulling it out, and avoid using excessive force to prevent wire breakage. After removing the pedal entirely, don’t forget to clean the accumulated dust in the pedal slot to prevent sticking during reinstallation. If it’s an electronic pedal, also check that the sensor connection is secure. The entire process takes about 20 minutes, and simple tools like a wrench and flashlight are sufficient. Beginners may take longer if they’re unfamiliar—don’t rush. After reassembly, test the static rebound before driving to ensure responsive throttle feedback. Extra tip: Take photos during disassembly to avoid confusion when reinstalling. Regular pedal inspections can prevent lag issues.
