Dtc P0133: O2 Sensor Circuit Slow Response / Performance (Sensor-1, Bank-1) - Suzuki 2006 SX4 Service Manual

Step
4 A/F sensor circuit check
1) Disconnect connector from A/F sensor and ECM with
ignition switch turned OFF.
2) Check for proper connection of each A/F sensor circuit
terminal to A/F sensor connector and to ECM connector.
3) If connections are OK, check A/F sensor circuit for the
following.
• Resistance of each sensing circuit wire of A/F sensor
between A/F sensor connector and ECM connector is
less than 2 Ω
• Resistance between sensing circuit wires of A/F
sensor connector are infinity
• Resistance between each sensing circuit wire of A/F
sensor connector and vehicle body ground is infinity
• Voltage of between each sensing circuit wire of A/F
sensor connector and vehicle body ground is 0 V with
ignition switch tuned ON
Is it in good condition?
