(b) The VALVE-PRESSURE HOLDING (218QM) (VALVE-PRESSURE HOLDING (219QM)) (Ref. AMM TASK 28-16-43-000-001) and (Ref. AMM TASK 28-16-43-400-001).
(2) Do the test given in Para. 3.B.
(3) If the fault continues, do a check of the fuel recirculation (cooling) pipe for damage or blockage. Replace, if necessary (Ref. AMM TASK 28-00-00-000-001) and (Ref. AMM TASK 28-00-00-400-001).
(4) Do the test given in Para. 3.B.
