Question about 1994 Toyota Celica

3 Answers

My engine check light is always on. I took it to Toyota, and they said I needed a new Oxygen sensor, which is an expensive replacement. I am an acquaintance with one of the mechanics there, and he said that it was just a screw-on-gas-cap problem. He said to turn it so that it clicks about five to 10 times, and within a while, the light will go out. That may be, but, the engine check light is an important indicator for other things. Any ideas on gas-cap idea?

    Thanks, but, I am incorrectly listed. as having a 1994 Toyota Celica. I have a 2002 MR2 Spyder. The O2 sensor isn't expensive, but, I'm gold the engine has to be moved or removed to replace the sensor, making it quite expensive

The gas cap thing is something worth doing... an O² sensor isn't too bad... maybe $40 for the part?

    Thank you. I don't have a 1994 Celica. I have a 2002 MR2 Spyder. The O2 sensor may be OK price wise, but, I am told that the engine must be moved or removed to replace the sensor, making it quite expensive. Toyota knows about this problem, I'm told with the gas caps, and still replaces the O2 sensor, and, the next time you fill up, the check engine light is back on.

The O2 sensor is not that expensive. If you replace it yourself. Buy one at your local auto parts store or from Toyota. The sensor should be between the exhaust manifold and the cat. converter. You can use a wrench or a special "O2 socket" to remove it.

Catalytic converter or Oxygen sensor


If you smell rotten eggs its usually the cat is stopped up. Go to rockauto.com and look it up, you can try the O2 sensor there also. Just bought an O2 for my Toyota for $19.

2007 Toyota sienna V6 P2197 code from Autozone diagnostic.


Solved. I have 2008 Sienna with Check Engine and VSC lights on. Scanned codes were P0051 and P2197. Oxygen Sensor Bank 2 Sensor 1 needs to be replaced. You can see this sensor on the right side of the engine when you open up the hood. You need to get an Oxygen Sensor socket (I used Tekton 7/8in 22mm which costs $9) and a wrench extension to reach it. Spraying liquid wrench a few times on the base of the old sensor also helped to loose it. The replacement sensor I used was Denso 234-9049 which costs $85 from eBay. Lights went off after the sensor was replaced. It took me 30 minutes to replace.

1996 Toyota 4runner 3.4L error code p0133


SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

2002 Toyota Highlander 2WD, 4 cylinder


Welcome to FixYa. I'll be glad to help you out.

Code P-1150 indicates an Air-Fuel sensor range/performance issue.

The air fuel sensor is similar to an oxygen sensor, but it does a different job.

Without in-depth analysis on a scan tool that can read the output of the A/F sensor, it is hard to tell you exactly what is happening, but prior experience indicates that you probably need to replace the A/F sensor.

You would do well to purchase a genuine Toyota A/F sensor, as the cheaper 'aftermarket' units do not perform well; your check engine light may remain on after you replace the sensor with an aftermarket

Thanks for choosing FixYa for advice.

Autozone oxygen sensors do not function properly in Toyota vehicles. Just had a Tacoma yesterday with the same issue. New sensors, runs poor, check engine light on. Toyota sensors fixed it right now.
