2003 CVR oxygen sensor

With my engine light coming on again, a local garage told me I need to replace two (primary and secondary) oxygen sensor(s). Is this something that can be cleaned rather than replaced?

No cleaning,got to replace.

I would be suspect that two failed.
I would want to know what set the O2 Codes. The codes may be the symptom and not the fault. e.g. something caused the sensors to go out of range and set a code.
Something may, over time be fouling the sensors,IF they are bad.

Typically no. these are a wear out item. the internal grounds tend to break down, rendering them ineffective, or the wiring harness can become damaged. in your particular vehicle, i have come across many 02 sensor issues that have been solved by replacing. good luck!

Primary oxygen sensor

If the car is running fine, don't go chasing a yellow light with expensive repairs you don't need. Simply perform an OBDII scan of the stored fault history. Also get a print out of the existing faults, if any are present. Delete the fault history from the ECU memory, and go from there. On some vehicles the annoying yellow light comes on when you reach a preset mileage just to get you back to the dealer, for no reason. Let the ODBII scan be your guide, to avoid buying parts you don't need.

Primary oxygen sensor

The o2 sensors don't do anything untill the car is up up operating temp. After that they fine tune the fuel mixture,if they were bad,you should see a small decrease in fuel mileage.They do wear out ,like a battery kinda,but not usually both at the same time. The front one "takes a reading" then the rear one, the computer figures out if there is too much or too little o2. So anything wrong with the engine,like a bad spark plug wire, exhaust leak ,vacuum leak or
bad fuel could set those codes. If it still runs fine,like you say,I would first think of a fuel problem,lots of corn in the gas these days,run it down to 1/4 or so ,fill it with good fuel and add some deicer "heat" or similar. The O2 code won't shut the car off or anything, won't leave you stranded,the light is on because the emissions levels are above the preset limit in the computer.
Hope there's some help here ,maybe someone else will chime in ......

Had ignition coils replaced. enging light back on. wasd told now i have to replace cat conv. at 102,000, and had a/c replaced, timing belts and all other 105,000 services already! $3,000 later now I...

The cat is the primary part for cleaning up your emissions. Like any bad part on a car if it is not replaced in a timely manner it can lead to other parts going bad, such as the oxygen sensors. It can also negatively effect your gas mileage, because the computer determines fuel off of the oxygen sensors. The check engine light should also be on preventing you from passing inspection(if your area has an emissions inspection).

Check engine light said 2nd air supply . garage said oxygen sensor , they replaced it and had to replace manifold also, they said problem with this model the sensor won't come out of manifold with out...

2nd air supply is not a oxygen sensor problem, they screwed up, and also ive done many with frozen oxygen sensors,you heat the manifold to remove i even had some take the threads out and i retapped them,this code is a bad airpump or a secondary air flow valve.they misdiagnosed the problem and now its going to cost more than it should have,they guessed!!!where not talking about a $50.00 mistake where talking hundreds of dollars,they have to do something, eat the parts they put in,give you a refund for that or repair this problem for free,no ones perfect everybody makes mistakes, just own up to them when you do. good luck.

Fuel to rich bank 1

Change the primary oxygen sensor on the number one cylinder bank. Whichever bank has cylinder number one, is bank one. The primary sensor is the one between the engine and the catalytic converter on that side. There's a secondary sensor behind the catalytic converter, but the primary (pre-cat) sensor is the one used for determining fuel mixture.
