[1] Zero quantity calibration for the injector of cylinder 2: The maximum actuation period of the injector was exceeded.

[1] Zero quantity calibration for the injector of cylinder 2: The maximum actuation period of the injector was exceeded.

Test 1: Possible cause and remedy

1. Possible cause and remedy

Test 1.1: Test of compression

Test 1.2: Check the zero quantity calibration.

1.1. Test of compression
Test prerequisites

- Engine not running
NOTE RE Test of compression

- From an engine speed difference of more than 5 1/min, a mechanical compression pressure test and cylinder leaktightness test must be carried out at all the cylinders in order to pinpoint the fault.


Warning!Communication with ECU required.


1.2. Check the zero quantity calibration.
Check component Y76y2 (Fuel injector cylinder 2).
Tests conducted

- Compression test
Possible cause and remedy

- Replace component Y76y2 (Fuel injector cylinder 2).
