It doesn’t matter much because I bought one so it’s what I use.

So far, I will say I do like mine. Haven’t had it long and have had no problems.

I also have a car that is sending error codes. They have basically been covered. I searched on how to reset the ecm but haven’t had a chance yet.

Probably end up taking it to a dealer.

Actually went to a tech school years ago, but with all the changes it might just as well have been for Model A’s.

There is an error code that accompanies the check engine lite. This tells you where the problem is located.
My truck you need to turn the ignition to accessory then off 3 times then the error code shows up.

Then you can determine what to fix.

Few examples: Something as simple as a leak in the emission system can cause an error code, a loose gas cap. Then you wasted $$ on replacing a sensor. 80’s model toyotas were this way, newer model have a computer than generates an error code.

Lets say me error code is a P0171 for a 2004 toyota tundra.
Search google for “2004 Tacoma error code P0171″, then you will get some results of what people did and how they fixed it.

Hope that helps

Indicating that it was poor emissions produced by poorly firing spark plugs. The sensor detected the poorly burned gasses, set off the light, but once the engine was burning the gasses correctly, the light went off.

6 spark plugs costs way less than a new sensor, especially when the end result would be new spark plugs anyway.

Most of the research I have done indicates that they are as good or better than Cobra, which was always my radio of choice and are comparable in price.
