The vehicle speed sensor (VSS) or output transmission speed sensor determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission or at one of the wheels if the signal is coming from the ABS module to the PCM or TCM. The speed sensor can produce analog waveform signals or square wave Although generic, the specific repair steps may vary depending on make/model. A P0222 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V). The B refers to a particular circuit, sensor, or area of a particular circuit. The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts. 50 people reported this problem. 2 comments.

The tps is located on the throttle body it should be on the drivers side of the vehicle and located near the front of the throttle body housing. It is usually black bakelite or plastic material and has a 2 or 3 prong quick disconnect plugged into and held inplace with 2 or 3 Most throttle position sensors are potentiometers – a three- sensor with a reference voltage (5 volts), a signal return (ECM/PCMground), and a TP signal wire between those voltage and ground feeds that changes voltage with throttle position. On systems with redundant TP sensors, the two or three sensors don’t all produce the same voltage at Move the throttle and look for smooth meter response up to the 4.49 at WOT. The other wire will be the ground and should show no voltage. Perform the test procedure again and wiggle and/or tap on the TPS while you watch the meter. If you notice any flat spots or abrupt changes in the meter readings, replace the TPS. In this video, you will learn 5 symptoms of a bad accelerator pedal position sensor.
