Intermittent Codes

A diagnostic trouble code that is not there every time the TCM checks the circuit or function is an "intermittent" code. Some intermittent codes, such as codes P-1792(12), P-1767(14),P-1768(15), P-0725(18), P-1716(19), P-1781(21), P-1782(22),P-1724(24), P-0705(28), P-0120(29), P-0750(41),P-0755(42), P-0760(43), P-0765(44), P-1793(48),P-0715(56), P-0720(57), P-1794(58), P-1796(70),P-1799(74), P-1739(76), P1717(77), and P-0600(78) are caused by wiring or connector problems. However intermittent codes 50 - 54 are usually caused by intermittent hydraulic seal leakage in the clutch and/or accumulator circuits. Problems that come and go like this are the most difficult to diagnose, they must be looked for under the specific conditions that cause them.
