Not so. (See workshop manual D:04:10 System Control Monitors, bottom 
of page) In other words if you disconnect the O2 sensor or short 
circuit the sensor lead the Lamda ECU will continue to send a fixed 
voltage to the frequency valve resulting in continued operation. Most 
non-working frequency valve conditions are related to circuitry 
problems. i.e. A broken wire, connector problem, or defective 
component. Refer to D:04:12 items #1, 2, and 3 to locate the source 
of the problem.
