DESCRIPTION The millimeter wave radar sensor assembly receives accelerator pedal position sensor signals from the ECM to determine if the accelerator pedal is being depressed. If the ECM detects a malfunction in the accelerator pedal position sensor or SFI system, the millimeter wave radar sensor assembly is notified via CAN communication and stores DTC C1A63.
PROCEDURE
HINT: If DTC C1A63 is output by the pre-collision system, perform troubleshooting for the SFI system.

Toyota Tundra Service Manual > Sfi System: Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor) (P0327,P0328,P032C,P032D,P0332,P0333,P033C,P033D)
DESCRIPTION A flat type knock sensor (non-resonant type) has a structure that can detect vibrations between approximately 5 kHz and 15 kHz. Knock sensors are fitted onto the engine block to detect engine knocking. The knock sensor contains a piezoelectric element which generates a voltage when it be ...
