Why do you need a wiring diagram for a O2 Sensor? They are 4 wires and when you replace the sensor, you get a OEM. If you are going to get a Universal, it comes with a wiring diagram (GREY go to WHITE) and Black to Black

The wiring diagram shows the wiring color code, Power rating and connector plug used. The wiring diagram explains the vehicle's electrical connections with color code. It's a bit complicated to understand.

SOURCE: can only find oxygen sensor on rear exhaust fork

Normally you'll find at least one before the catalytic converter & after. You'll have to look real close at manifolds as they route from cylinder head then down , and then follow exhaust pipes to & after catalytic converter.

you will find it on the exhaust pipe, usually in front of the car. It's the only sensor(s) that's on the exhaust. Some cars have 2 of them, one before and one right after the catalitic converter.

My 2000 Cadillac Deville engine light on. Engine code PO420

Catalyst System Efficiency Below Threshold (Bank 1)

A code PO420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of reading

  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

Change oxygen sensor

Under hood, center, front engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Front
Under hood, center, rear engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Rear

The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.
  1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
  2. Detach the electrical connector from the oxygen sensor.
  3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.


NOTE A special anti-seize compound is used on the oxygen sensor threads. The compound consists of liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If an oxygen sensor is removed from the engine and if for any reason, it is to be reinstalled, the threads must have this anti-seize compound applied before installation.
  1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
  2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
  3. Reattach the electrical connector to the sensor and the negative battery cable.
