Detection Condition

WARNING: This page is about a different car, the 2003 Mazda Protege5 and 2003 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors input voltages from VTCS solenoid valve. If voltage at PCM 73 is high when the VTCS solenoid valve ON, PCM determines that VTCS solenoid valve malfunction.

Monitoring Conditions

Engine speed is less than 3250 RPM.
Engine coolant temperature is less than 149°F (65°C).
Throttle valve opening angle is less than 14 percent (A/T) or 12.5 percent (M/T) at 2500 RPM.

This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
