Engine General Information and Diagnosis: 1A-119
5 1) If the EXCVA position sensor output voltage is 0.45 V
and less at EXCV fully closed position, adjust the output
voltage to the specified value by turning the No. 1 cable
adjuster (1). Refer to “EXCV Cable Removal and
Installation” in Section 1K (Page 1K-6).
2) Repeat the procedure in Step 4 until the output voltage is
set within the specified value. (If C46/P1657 code is
indicated after adjusting the voltage, increase the
voltage to 0.9 V).
CAUTION
!
• Adjusting the cable with the EXCV fully
opened or fully closed can damage the
EXCVA. Be sure to adjust the cable with the
EXCV set in the adjustment position. Refer to
“EXCV Cable Removal and Installation” in
Section 1K (Page 1K-6).
• Do not turn the EXCVA pulley using a wrench.
3) If the EXCVA position sensor output voltage is 4.55 V
and more at EXCV fully opened position, adjust the
output voltage to the specified value by turning the No. 2
cable adjuster (2). Refer to “EXCV Cable Removal and
Installation” in Section 1K (Page 1K-6). Repeat the
procedure in Step 4 until the output voltage is set within
the specified value.
EXCVA position sensor output voltage
EXCV is fully closed: 0.45 ≤ Output voltage ≤ 1.4
EXCV is fully opened: 3.6 ≤ Output voltage ≤ 4.55
Is the voltage OK?
Replace the ECM with a
known good one, and
inspect it again.
Replace the EXCVA
with a new one.
Step Action Yes No
