How many o2 sensors are on a 1999 Silverado 5.3


The 1999 5.3 V8 engine had 4 oxygen sensors. There are two catalytic converters on this engine, one on the driver side of the engine, and one on the passenger side of the engine. This is important to know, as the number of oxygen sensors is directly related to the number of catalytic converters on the vehicle. Driver side is referred to as Bank 1, passenger side is referred to as Bank 2. This is very important to know when looking up replacement oxygen sensors. There is one oxygen sensor in front of, or before the catalytic converter, usually referred to as a pre-catalyst O2 sensor. There is also one behind, or after the catalytic converter, usually referred to as a post-catalyst oxygen sensor. So, you have two oxygen sensors on Bank 1, and two oxygen sensors on Bank 2, for a grand total of 4 oxygen sensors.

Code of PO174 1 system too lean (bank 1) Code PO420 Catalyst efficiency below threshold (bank 1) Code PO430 Catalyst efficiency below threshold (bank 2)


hi,my friend, you can try,

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

I have an 03 Camry 4cyl LE that needs an O2 sensor. Does this model have more than one sensor? I have gotten conflicting info about the number of sensors and corresponding pns.


YOU HAVE 2 OXYGEN SENSOR UPSTREAM OXYGEN LOCATED ON THE EXHAUST MANIFOLD. THE DOWN STREAM OXYGEN SENSOR LOCATED BEHIND THE CATALYTIC CONVERTER.YOU CAR HAS ONLY 2 OXYGEN SENSORS.

The check engine lamp on my vw jetta 3 is ''on'', i put a diagnostic reader on and it showed the following codes:P0422,P0411,P0300B,P0301B,P0302 and P00172B, what do they mean and how can i solve the...


P0422 - Catalyst below threshold.

Catalytic converter is clogged or out of medium.

Replace it.


ACTUAL DIAGNOSTIC:

Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter's emissions efficiency has fallen below the minimum allowable limit. This threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on or near the outlet of the Catalytic Converter.

Symptoms

* Check Engine Light will illuminate
* In many cases, no abnormal symptoms may be noticed

Common Problems That Trigger the P0422 Code

* Defective Catalytic Converter
* Engine misfires have damaged the Catalytic Converter
* Internal engine damage resulting in high oil consumption and/or a leaking Head gasket has damaged the Catalytic Converter

Common Misdiagnoses

* Oxygen Sensors are replaced when the real problem is a damaged Catalyst
* Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
* Catalyst is replaced when a misfiring engine is the real problem

Install heated oxygen sensor number 1 in volswagen jetta


Hi:
The Number 1 Heated Oxygen sensor is located in front of the catalytic converter. You would need to get the car up in the air, and then disconnect the electrical connector, and possibly need a special socket to remove the sensor. Also remember to purchase and use Oxygen sensor safe anti sieze compound on the threads of the new sensor, if you do this your self

Check engine light on for sometime; Response to throttle sluggish


If your catalytic converter is "below efficiency" or otherwise clogged, you will lose power as you drive and the vehicle heats. The more you drive the vehicle, the worse the problem will become. The exhaust can't escape properly through the catalytic converter, therefore your engine won't run properly. Your issues are related, and if you replace your catalytic converter they should go away.
