Dz11 Check The UO2S, UO2SGREF, UO2SPC, And UO2SPCT Circuits For A Short To Ground In The Harness

Measure the resistance between:

( + ) Universal HO2S Connector, Harness Side	( - )
UO2S - Pin 6	Ground
UO2SGREF - Pin 2	Ground
UO2SPC - Pin 1	Ground
UO2SPCT - Pin 5	Ground

Are the resistances greater than 10K ohms?
- Yes: GO to DZ12 .
- No: REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.
