There are 2 O2 sensors...
One is in the exhaust manifold ,rear of the engine, in manifold by firewall.
The other one is in the exhaust behind the catalytic converter.

Hey Guest. Please post the exact code number that was read to make them tell you the O2 sensor is bad. A lot of times the O2 is good ans something else causes the problem. Here is a partial list of O2 codes. This does not include manufacturers codes. You can see why we need the specific code. The last 4 are not for O2's, but a lot of parts houses wilol sell the sensor to try to clear the code. Remember, the parts person is probably NOT a technician/mechanic.
P0131 Upstream Heated Oxygen Sensor circuit out of range - Bank No. 1. P0132 Upstream Heated Oxygen Sensor circuit Voltage High - Bank No. 1. P0133 Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 1. P0135 Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1. P0136 Downstream Heated Oxygen Sensor circuit fault - Bank No. 1. P0138 Downstream Heated Oxygen Sensor circuit Voltage High - Bank No. 1. P0140 Downstream Heated Oxygen Sensor circuit Faulty - Bank No. 1. P0141 Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1. P0151 Upstream Heated Oxygen Sensor circuit out of range - Bank No. 2. P0152 Upstream Heated Oxygen Sensor circuit Voltage High - Bank No. 2. P0153 Upstream Heated Oxygen Sensor circuit Slow Response - Bank No. 2. P0155 Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2. P0156 Downstream Heated Oxygen Sensor circuit fault - Bank No. 2. P0158 Downstream Heated Oxygen Sensor circuit Voltage High - Bank No. 2. P0160 Downstream Heated Oxygen Sensor circuit fault - Bank No. 2. P0161 Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2. P0171 System Too Lean - Bank No. 1. P0172 System Too Rich - Bank No. 1. P0174 System Too Lean - Bank No. 2. P0175 System Too Rich - Bank No. 2.

P1404 is an EGR code
Possibilities are faulty EGR valve, PCM, wiring/connections..
The oxygen sensor itself its the "heated oxygen sensor"....
see above diagrams......

If you have an EGR code, that can cause an O2 code due to the wrong mixture of fuel and air going into the engine. If the mixture is wrong going in, it has to be wrong coming out and the O2 sensor can pick up on that. Your code is for the O2 sensor heater. That usually is the sensor itself. On the EGR code, have the EGR removed and check to see if carbon is on the pintle holding the valve from operating.
