Mazda - Protege :: 2001 - What Does A Pink Oxygen Sensor Tip Indicate
Jun 26, 2011
I have a 2001 Mazda Protege LX 2.0 with 121,000 miles. I removed the front oxygen sensor today to replace an exhaust pipe, and I noticed that the tip has a red/pinkish color on one side only. What this would indicate?
The only thing I could find online is that a pink tip indicates lead in the fuel. This is impossible, since the only gas station I frequent is a Conoco which is always very busy. Plus, I haven't noticed any performance issues from bad gas, and not to mention the fact that leaded fuel has been completely phased out for 15 years. What's weirder is that the sensor tip is only pink on one side - I'm guessing it's the side that's facing the exhaust manifold.

1996 Mazda Protege has 125,000 miles. Checkup this spring noted that the engine oil sensor was leaking, but did not note if a problem. I check the oil monthly with no problems with the oil going down. Many posts about engine oil pressure fixes, but none about leaking issues. What happens if I ignore the problem?

I have sel code of P0421. What are the odds of the downstream sensor being bad vs a bad catalyst converter? The car runs great and I get 19+ mpg in town driving. It is a 2001 Mazda Protege, 2.0L V4 .....

Would hitting the upper catalytic converter with a rubber mallet free up anything that may be causing the P0421 error and CEL to come on? I need to know if it would do any good or any harm.

Last year I posted my CEL problem of P0421 and replaced both upstream and downstream sensors. I passed smog because I was allowed one error message and that message was Cat not ready. I had cleared the CEL light and drove long enough before inspection to reset all but the Cat not ready message and no CEL.
Last Friday I had to clean my throttle body butterfly valve and interior housing and I also had to replace the air inlet hose that connects the air cleaner/MAF sensor to the throttle body because the hose had some splits allowing air in. I disconnected the battery before doing any work.
My new question: Could air entering freely through the splits in the inlet hose, thus bypassing the MAF sensor, and being delivered directly to the throttle body, cause an error message of P0421?

2001 Mazda Protégé 2.0 LX model.
When I turn on the AC I can hear the compressor working. When the fan speed is 1, 2, or 3 the AC button is green, the compressor is working but no air is coming out of the vent.
When I turn the fan speed knob to 4 the AC button light goes out and I have air flow from the vent. The hose from the compressor is cold to the touch but the air coming out of the vent on 4 is not cold.

In California, if my OBC11 reader shows, "Cat Not Ready" and all other systems are "Ready" will it pass the smog test for an enhanced area?
In other words, do all systems need to show, "Ready" or am I allowed one or two "Not Ready"?
I do not have CEL on.

I have a 2001 ford explorer sport and realized that the oxygen sensor on the passenger side behind the cat was unplugged from the harness.
I am unable to find the harness and dont know where its supposed to go.
I would like to get this fixed right away but can not find a diagram anywhere, or a manual...

Lately, when first starting my car and after it’s been sitting for a while the gas pedal seems to be stuck.
When I push on it slightly it doesn’t move; but if I push a little harder it will make a noise and become free and movable. No further problems until it sits for a while or the next morning. Then the same stuck pedal. Exert a little pressure and it frees up.
I tried squirting WD40 on the linkage but it does no good. What could cause it to bind up? 2001 Mazda Protege LX 2.0 ....

I just posted last week that my check engine light was on and the dealer wanted to replace fuel injectors. But after the fuel throttle was cleaned and oxygen sensor was replaced the check engine light went off. However, yesterday the check engine light came back on. I am talking it back to the dealer, in a couple of days. Where can I go to get to get the error codes read so I have them before I go back to the dealer? Around 128,000 runs fine, around 40 miles per gallon. Last time I had the oil change dealer nothing came up on the 30 point inspection.

I have a 2001 Exrursion 5.4L V8. The code P1131 comes up and it says "Lack of upstream heated oxygen sensor switch - sensor indicates lean - bank #1". I hear it could be the sensor that is bad or there is a vacuum leak. It runs like a champ, no spitting, no sputtering, no missing, no ruff idle. What do I need to do to fix it or where do I need to start looking?

I have a 2010 Toyota Corolla 1.8L, the base model.
I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.
Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?
Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

The service truck threw a CEL, and i pulled oxygen sensor performance bank one sensor one code. That would be driver side sensor between the manifold and cat, rite? Don't want to change the wrong one...

Have 2002 mazda protege 5 . During acceleration at 3000 rpm the engine hesitates. Computer said o2 sensor, replaced it but that wasn't it. Drilled out both catalytic, that wasn't it. Found hole in mass air flow tube, figured that is it. I haven't replaced that yet, however I used gorilla tape thinking it would be a temporary fix but that didn't work. I know I need to replace that tube, but think that it may now be a fuel pump issue??

I have a 1999 Mazda Protege. As of last summer it started giving me problems with not wanting to start after I had driven it around town for a little while. (IE: to the grocery store, to the bank and then to my sister's house. It wouldn't give me the same problem if I just went to the grocery store and back home. It would start up fine and I'd be on my way. Only when I went somewhere and shut it off then repeated that a couple more times.) I took it to a mechanic who wholeheartedly believed it was the coil packs not allowing my car to function properly.
So we replaced those and everything seemed on the up and up. (Keep in mind that this was towards the end of summer and the temperature was dropping.) The car was perfect all throughout the fall and winter, but now that the temperature outside is starting to rise again it's beginning to do the same thing it did last summer. I don't want to take it to another mechanic that's going to have me dish out an extravagant amount of money again only for the problem to persist.

2000 Mazda Protege ES 1.8L
What's a good way to find whats the cause of all the rattling and knocking in the front end of my car when going over uneven terrain? It seems that noise appears only if one of the wheels is lifted up a little bit. I am attaching a picture describing the "motion" here:
Steering wheel doesn't shake when driving at high speeds and is fairly stiff, but it does pull to the right a bit, maybe because I didn't perform a front end alignment (I know this is not good) after I had most of the stuff in the suspension of the replaced; all 4 struts + boots + mounting blocks, ball joints, control arms...
Now the only part, I didn't replace was the sway bar link on the passenger side and it's being knocking for 3 years. The one on the driver side was replaced at the time the struts were replaced but I didn't have enough money to pay for the other one.
Another mechanic told me when I was quoting that sway bar links aren't really necessary as a safety feature, and a google search showed me that there are people that just take the sway bar off the car, so I left it there and just tried to live with the noise. now I am noticing the driver side is knocking as well, and I am wondering if it has to do with because I didn't replace the one in the passenger side?
I just want to rule out the possibility of another component being the cause of the noise because I am prioritizing safety over ride comfort in my attempts to save some money.

it was over 100 degrees today in Lawrence, Kansas and on the way home from work, the air conditioner stopped making cool air. Hot air now comes out. This is a different problem that the poster before me seems to have. Mazda Protégé, 1996, 128,000 plus miles on it.
A reconditioned one was installed in 2006, compressor replaced in July, 2012.
