Repair wiring and cable terminals, using appropriate procedures. 
In theory, the resistance across contacts, leads and terminals should be 0 [ohm]. However, there is always some resistance due to terminal oxidation.
If this resistance becomes too great the result will be a malfunction. The magnitude of the resistance before it causes a malfunction depends on the circuit
load.

Checks:

-

Check the cables visually according to "Check Terminals Visually."

 

NOTE:  Do not apply rust solvent spray or grease to the Heated Oxygen Sensor (HO2S) or combined instrument panel connectors.

-

Ignition off

-

Disconnect the battery negative terminal

-

Use compressed air to clean the disconnected connector

-

Apply rust solvent spray 1161422 to the disconnected connectors

-

Blow clean using compressed air.
