Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Note On Intermittents
If PCM Code E013 is stored as a history code, start engine and enter diagnostics. Operate engine at fast idle until AUTO "closed loop" status light is turned on. Observe parameter of ED33 while manipulating wiring on circuits No. 412 and 413. If parameter ED33 changes from a fluctuating voltage to fixed .45 volt, repair intermittent open circuit.
Check circuit No. 413 for a good ground to engine (clean and tighten star washer). Ground for circuit No. 413 is located at right side of engine or rear of cylinder head.
