The fuel pressure sensor of the low pressure circuit has a short circuit to positive.
Test 1: Check component B4/7 (Fuel pressure sensor).
Test 2: Possible cause:
- B4/7 (Fuel pressure sensor)
Affected functions:
- Engine diagnosis
- Fuel system
1. Check component B4/7 (Fuel pressure sensor).
Test 1.1: Check component B4/7 (Fuel pressure sensor) using actual value.
Test 1.2: Check power supply of component B4/7 (Fuel pressure sensor).
Test 1.3: Test wiring to component B4/7 (Fuel pressure sensor).
1.1. Check component B4/7 (Fuel pressure sensor) using actual value.
Warning!Communication with ECU required.
1.2. Check power supply of component B4/7 (Fuel pressure sensor).
Test prerequisite
- The actual value is not o.k.
Test sequence
- Switch off ignition.
