Throttle Position (TP) Sensor
Unplug connector from TP sensor, located on VAF meter. Connect ohmmeter to sensor terminals TP and SIGRTN (Orange and Blue/Yellow wires on mating connector). Measure resistance at each throttle opening specified in THROTTLE POSITION (TP) SENSOR RESISTANCE table. Replace sensor if resistance is not within specification.
