TP SENSOR-B1
(Throttle/Pedal position
sensor/switch “A” / “B”
voltage correlation)
Rationally incorrect voltage is sent to ECM
compared with the signals from TP sensor 1
and TP sensor 2.
• Harness or connector
(TP sensor 1 or 2 circuit is open or shorted.)
• Electric throttle control actuator
(TP sensor 1 or 2)
