Checking the fuel pressure control valve of the high-pressure fuel pump (Mazda BT-50 (1))

1. Disconnect the cable from the negative terminal of the battery.

2. Disconnect the fuel pressure regulating valve connector.

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

• Resistance - 2.6 - 3.15 Ohm

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