Checking wiring and connectors

Caution! Do not apply rust solvent spray or grease to the heated oxygen sensor (HO2S) connector.

Check signal cable (+) between control module #A42 and heated oxygen sensor (HO2S) connector terminal 4 for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
