What is PGM-FI sub relay?
The PGM-FI Main Relay is actually comprised of two individual internal relays. This ground triggers one of the PGM-FI internal relays that sends battery voltage to the fuel pump for two seconds to pressurize the fuel system. When the engine is running the PCM supplies a continuous ground to the PGM-FI Main Relay.Jun 10, 2020
Where is the PGM-FI relay located?
The Programmed Fuel Injection (PGM-FI) main relay in Honda CR-Vs manufactured between1997 and 2000 is located on the passenger's side behind the dashboard and glove box.
