DESCRIPTION The No. 3 ultrasonic sensor sends and receives ultrasonic waves. Based on the received wave, the sensor calculates the approximate distance value between the vehicle and the obstacle, and sends the distance value as a signal to the clearance warning ECU assembly. WIRING DIAGRAM PROCEDURE
(a) Replace the No. 3 ultrasonic sensor (rear center sensor RH) (See page ). (b) Inspect the No. 3 ultrasonic sensor (rear center sensor RH) (See page ).
(a) Disconnect the S3 No. 3 ultrasonic sensor (rear center sensor RH) connector. (b) Disconnect the S4 No. 2 ultrasonic sensor (rear corner sensor RH) connector. (c) Measure the resistance according to the value(s) in the table below. Standard Resistance:

Toyota Tundra Service Manual > Automatic Transmission System: Gear 6 Incorrect Ratio (P0729)
DESCRIPTION The ECM uses signals from the output speed sensor SP2 and input speed sensor NT to detect the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear). Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift solenoid va ...
