I purchased this item 2 months ago from another vendor not realizing CARiD also sold them.
I installed item on my 2013 Scion tC on Sunday and ran my code scanner to reset the obd 2 computer and everything ran smoothly until today. Then the check engine light came on and my car stalled so I put the stock maf sensor back on so I could get home. I then attempted cleaning the jet flow with maf sensor cleaner let dry.
Then I attempted to reinstall but each time the check engine light came on and it ran funny and my Zurich was unable to clear the codes. It was not until I read here how someone else had the same issue and disconnected the sensor and the battery for 5 minutes, then plug the harness back into the sensor first then reconnect the positive and negative terminals on the battery. Turn key to the on position. Then run clear all oem enhanced and obd 2 codes to reset computer further. Then start car let run for 5 minutes at idle.
Then turn off engine turn key to on position to clear new pending codes from computer which are the engine startibility codes that get set from the computer remapping and relearning from the new high performance sensor.
Then restart car, then drive it around to get all monitoring systems back to ready.
Anyway the Idle on these things is much smoother vs the stock denso sensors. And the car runs much better now vs the stock denso sensor. Thank God someone posted about disconnecting battery before installing this great sensor.
I thought the sensor went bad when the low circuit code went on. And the needing to let the cars computer relearn and remap so the sensor works Iike it should. Still curios why car did not set off any codes for 4 days.
And then today even with a computer reset from my good Zurich scan tool it made the engine and idle go haywire every time I tried reinstalling the sensor until I disconnected the battery for 5 minutes first.
