The HDS or the scan tool indicates Diagnostic Trouble Code (DTC) P0133: A slow response problem in the Right

Primary Heated Oxygen Sensor (Right Primary H02S) (Bank 1, Sensor 1) circuit.

The HDS or the scan tool indicates Diagnostic Trouble Code (DTC) P0153: A slow response problem in the Left

Primary Heated Oxygen Sensor (Left Primary HO2S) (Bank 2, Sensor 1) circuit.

Description

By controlling the air/fuel ratio with a Primary HO2S (Sensor 1) and a Secondary HO2S (Sensor 2), the deterioration of the

Primary H02S (Sensor 1) can be evaluated by its feedback period. When the feedback period of the H02S exceeds a certain

value during stable driving conditions, the sensor will be judged as deteriorated. When deterioration has been detected dur-

ing two consecutive trips, the MIL comes on and DTC P0133 or P0153 will be stored.

NOTE: If DTC P2195, P0134, P2297 and/or P0135 are stored at the same time as DTC P0133, troubleshoot those DTCs first,

then troubleshoot DTC P0133. If DTC P2197, P0154, P2298 and/or P0155 are stored at the same time as DTC P0153, trou-

bleshoot those DTCs first, then troubleshoot DTC P0153.

Possible Cause

• Primary HO2S (Sensor 1) Deterioration

• Primary H02S Heater (Sensor 1) Deterioration

• Exhaust system leakage
Primary Heated Oxygen Sensor (HO2S) (Sensor 1)

The Heated Oxygen Sensors (HO2S) detect the oxygen content in the exhaust gas and signal the PCM. In operation, the

PCM receives the signals from the sensor and varies the duration during which fuel is injected. To stabilize the sensor's

output, the sensor has an internal heater. The Right Primary HO2S (Bank 1, Sensor 1) is installed in the right exhaust man-

ifold, and the Left Primary HO2S (Bank 2, Sensor 1) is installed in the left exhaust manifold.ProCarManuals.com

OnStar System

OnStar Buttons and Microphone Input Test

'03 Model

1. Pry off the OnStar buttons and microphone/homelink buttons.

2. Inspect the connector and socket terminals to be sure they are all making good contact.

• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

• If the terminals look OK, make the following input tests at the connector.

— If any test indicates a problem, find and correct the cause, then recheck the system.

— If all the input tests prove OK, the switches and microphone must be faulty; replace it.

•: A3 and A4 terminals are microphone lines for navigation system.
