Timer Unit: Description and Operation
Vehicle Component Locations:
A
timer relay is used to inhibit the
distributor vacuum advance for 45 seconds after each engine start up. This is done to obtain a faster catalytic convertor "light off". The timer relay operates a solenoid vacuum valve that ports the distributor vacuum line to atmosphere, defeating
ignition timing advance.
