Intermittent Code
2002 Jeep Liberty Limited Edition 2WD V6-3.7L VIN KSECTION Intermittent Code
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 P0932(CA), P0891(14), P0888(15), P0725(18), P1694(19), P0841(81), P0846(82), P0871(84), P0988(88), P0876(90), P0750(C1), P0755(C2), P0760(C3), P0770(C4), P0765(C5), P2706(C6), P1793(48), P0715(56), P0720(57), P1794(58), and P1799(74) are caused by wiring or connector problems. However intermittent codes P0731(51), P0732(52), P0733(53), P0734(54), P0736(50), P0735(59), P1736(55) (Speed ratio codes) are usually caused by intermittent hydraulic seal leakage in the clutch and/or accumulator circuits. Intermittent speed ratio codes can be set by intermittent speed sensor circuitry or by line noise being induced onto one or both of the speed sensor signal 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.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
