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.
Notes On Intermittents
If code "E013" is a hard code, start engine and enter diagnostics. Operate at fast idle until "AUTO" closed loop status light is turned on. Observe parameter while manipulating circuit Nos. 412 and 413 wiring. If parameter PD07 changes from fluctuating to fixed at about .45 volts, repair intermittent open circuit.
Check circuit No. 413 ground to engine for proper installation (clean, tight and star washer installed). Ground for circuit No. 413 is attached to front of engine at right or rear of cylinder head.
NOTE: If Code E013 Is Accompanied By Hard Or Intermittent
Code E044 Or E045, See DFI Chart A-6
