Keenso 3 Output Transmission Sensor FN01-21-550, 2010 3 Transmission Sensor Output Car Vehicle Input Output Speed Sensor For 2/3/5/6/ CX-7/ Protege

Cleared issues it was ordered to replace. Hard to say how long it will last, but its been running for a week or so and no issues yet. AT light and check engine lights were clear the first time car was started after replacing the failed unit. Price is certainly much better than OEM, hopefully the part last for a while.

I'm not really sure what to say here...I bought it because my 2006 Mazda 3 was having problems shifting (up/down). Sometimes the shifting would trigger a few warning lights on the dash. I ran my code reader and it said I had a bad speed sensor (there are two on this car), so I bought this one. I switched it out, and now my car shafts as it should, still pretty smooth even with 174,000 on the odometer.

It's been a few months and so far no more shift or missed shift issues. Very pleased at this point. I had been to a highly thought of transmission shop twice for a random shifting issue. My car was throwing multiple codes. He showed me a blueprint of the transmission and I said I'll start with the easiest item first and work from there. If I hit a roadblock I'll be back. Fingers crossed, so far so good.

My engine light had been coming in for years and nothing seemed to fix it. Until I bought and installed this.

No le he instalado aun.

Shipped extremely fast and easy to install and great quality. Fixed my 2006 mazda 3 and no check engine light anymore.

UPDATE!!: its been 4 days. Yesterday starting having issues shifting. Now its shifting while parked and struggles in reverse. Having it towed to swap part for a real one from car manufacturer. Will see if that stops it. Had shifting issues with code P0715- turbine input /shaft speed sensor circuit.

Fixed my transmission shifting out of 4th to 3rd on the freeway for my 2004 Mazda 3

After finding what the problem was. Bought this speed sensor to replace the damage one. Never had a problem after that

Gracias a esta pieza me salvé de que me estafaran por casi 9 mil pesos, se veía algo sencilla pero hasta la fecha no me ha dado ningun problema

Este sensor ayudo muchísimo a mi transmisión de mi mazda 3 2004, los cambios ya no son bruscos pero las revoluciones en ralenti es inestable, este sensor quito las fallas de los cambios bruscos pero las revoluciones bajan y suben en ralenti, ya limpie el cuerpo de aceleración y sensor maf pero aún así la falla de revoluciones no se va. En fin lo que me importa más era que arregló la desaparición de cambios bruscos, la aparición de revoluciones inestables supongo que será otra cosa.

Worked without a problem but no idea on longevity. When installing, unplug wires on intake, don't just move them out of the way - ended up tearing Mass airflow sensor off. Remedied with bigger screws. Runs perfectly now.

Super product 🤘🏼
