DTC C101B-16/C101B-17: Vacuum Sensor 1 Circuit [EVP Control Unit]: Notes

DTC C101B-16/C101B-17: (EVP CONTROL UNIT) DETECTION CONDITION AND POSSIBLE CAUSE

DTC	C101B:16	Vacuum sensor 1 circuit low input
	C101B:17	Vacuum sensor 1 circuit high input
DETECTION CONDITION		C101B:16 If the EVP control unit detects that the vacuum sensor 1 voltage at the EVP control unit terminal AC is below 0.16 V for 0.6 s, the EVP control unit determines that the vacuum sensor 1 circuit has a malfunction. C101B:17 If the EVP control unit detects that the vacuum sensor 1 voltage at the EVP control unit terminal AC is above 4.9 V for 0.6 s, the EVP control unit determines that the vacuum sensor 1 circuit has a malfunction.
FAIL-SAFE FUNCTION		Refer to "Fail-safe function table". (See DTC TABLE [EVP CONTROL UNIT] .)
POSSIBLE CAUSE		Vacuum sensor 1 connector or terminals malfunction Short to ground circuit in wiring harness between vacuum sensor 1 terminal C and EVP control unit terminal AC EVP control unit connector or terminals malfunction Open circuit in wiring harness between vacuum sensor 1 terminal A and EVP control unit terminal AA Open circuit in wiring harness between vacuum sensor 1 terminal B and EVP control unit terminal Y Short to power supply in wiring harness between vacuum sensor 1 terminal C and EVP control unit terminal AC Open circuit in wiring harness between vacuum sensor 1 terminal C and EVP control unit terminal AC Vacuum sensor 1 malfunction EVP control unit malfunction
