Once you've cleaned the throttle body, it's time to reassemble everything. Ensure everything functions as it should, with no abnormal sounds or symptoms after the reassembly.
How to adapt your Ford Ranger's throttle body
For more recent Ford Ranger models, the throttle is often electronically driven (actuated by an electric pulse, rather than a cable). A designated throttle position sensor is tasked with tracking the throttle blade's position. Prior to starting the engine, this blade is ideally positioned at a straight angle of 90 degrees.
Perfectly aligned with the top and bottom walls, it allows no excess air to sneak in. However, over time, grime accumulates on the air channel's walls or on the blade itself. This dirt prevents the throttle from completely closing, keeping it stuck in a certain position.
The sensor interprets this position, and the Ford Ranger's computer assumes this as the new reference value.

In essence, the throttle blade's neutral position becomes its reference (factory) value, taking into account the layer of grime that has accumulated. This is completely normal, as it's a factory-provisioned setting designed to maintain the engine in a working condition.
But, once you've cleaned the throttle body and restored the surface to its initial state, the Ranger's computer might get 'confused'.
Without any indicators to inform it that nothing is hindering the throttle blade from fully closing, the vehicle's computer will still assume that dirt is present, maintaining the blade position it remembers.
This results in a gap between the throttle walls and the blade, enabling at least a few millimeters of air to pass through.
Subsequently, the Ford Ranger's computer 'believes' that the throttle pedal is perpetually pressed, even if it's not, allowing more air to enter the cylinders through this newly created space.
This can have adverse effects on the engine as it continually senses a load, particularly noticeable at idle when the rpm could jump to 1500–2000 rpm from the usual 800 rpm. This could lead to overheating and reduced engine life.
Therefore, after cleaning the throttle valve, it's necessary to recalibrate the blade to its factory position.
The throttle valve adaptation process is fairly universal for numerous Ford Ranger models.
Firstly, warm up the engine to the operational temperature, then switch it off and wait for about 5-10 seconds. Turn on the ignition and wait another 3 seconds. Following this, press the throttle pedal 5 times in 5 seconds, then release it.
If this doesn't seem to help, it's possible that your Ford Ranger's system has a different programming. The throttle valve adaptation algorithm should be documented in your Ranger's owner's manual.
To Wrap Everything Up
Cleaning your Ford Ranger's throttle body is crucial because it prevents dirt from accumulating on the blade or from creating gaps between the blade and the body itself.
During this cleaning procedure, patience and precision are key to attaining the optimal result.
