Checking the fuel pressure control valve injection pump

1. Disconnect a wire from the negative plug of the storage battery.

2. Disconnect the fuel pressure control valve connector.

3. Using an ohmmeter, measure the resistance between the valve terminals (at 20°С).

• Resistance - 2.6 - 3.15 Ohm

If the resistance between the valve terminals differs from the set value, have the injection pump repaired at a service center "Bosch".
