Suitable for Toyota Prius 2 generation.

Someone stole my catalytic converter and I had to replace it. It fits perfectly on my aftermarket catalytic converter from Ebay, very good and tight. The check engine light went out after I installed an aftermarket catalytic converter and O2 sensor. I had to drive it about 20km before the check engine light went out. O2 sensor successful and working!

Pros
  • Best in its niche
Cons
  • Empty

Don't waste money. Fits but does not work

This product fits the advertised vehicle. After I installed the product and cleared the engine fault code for the lower O2 sensor, the engine light came on again less than 10 minutes later with the same fault code, the lower O2 sensor is defective. I know this was junk because I bought and installed an OEM spec module. Worked as stated.

Pros
  • Excellent design
Cons
  • Other interesting options are available.

Put vehicle through emissions test

Vehicle received an error code through the downstream O2 sensors and failed the emissions test. The scan tool has confirmed that the downstream oxygen sensors are not working. Oxygen sensors 1 and 2 replaced downstream. Conducted a real-time scan, the sensors are working within the expected voltage. The car passed the emission tests without any problems. It is very useful to have heavy O2 sensor keys. Also warm up the exhaust system for a few minutes, be careful when working with hot exhaust…

Pros
  • Value for money
Cons
  • Commercial availability

2006 Prius Pending DTC Code P0420 Becomes DTC and Checks Engine

Designed to replace the OEM sensor with over 200,000 miles (but otherwise works fine) as part of the catalytic converter replacement to clean up 2006 year Prius for the smog- prepare test. . I ended up returning this and kept using the original for now (again - cat, original upstream and downstream O2 seem to work together - no codes). After a short drive, the Autel AL319 I/M Readiness Scanner shows a Pd (pending) DTC. The code scan returns P0420 (Catalyst system efficiency below threshold)…

Pros
  • Easy Tune
Cons
  • Null
