SERVICE PROCEDURE

NOTE
DTCS P013A / P013C INDICATING A LACK OF SWITCH ARE TYPICALLY A RESULT OF EXHAUST LEAKS OR EXHAUST MODIFICATIONS. EXHAUST LEAKS OR EXHAUST MODIFICATIONS WILL CAUSE CATALYST MONITOR SENSOR (CMS) OUT OF RANGE VOLTAGE READINGS. THE CMS SENSOR IS THE LEAST LIKELY CAUSE.

1. Inspect bank 2 (front of engine) Y-pipe ball and flare joint for exhaust leaks by restricting exhaust flow at the tailpipe. Also look for carbon soot and moisture witness marks indicating a leak at the bank 2 ball and flare joint.

2. If a leak is found replace the Y-pipe assembly.

3. Disconnect the left hand (LH) Catalyst Monitor Sensor (CMS) electrical connector.

4. Remove and discard the two (2) 10 mm catalytic converter-to-exhaust Y-pipe spring nuts and gasket.

5. Remove and discard the four (4) exhaust Y-pipe nuts, gasket and remove the Y-pipe.

6. Install service Y-pipe assembly, and bank 1 flat flange gasket, tighten four (4) exhaust flange nuts to 18 lb-ft (25 N.m) starting with flat flange on bank 1 and then ball and flare joint on bank 2.

7. Install catalytic converter-to-exhaust Y-pipe gasket and spring nuts, tighten to 18 lb-ft (25 N.m).

8. Recheck for exhaust leaks.
