Enhanced Denso 234-4749 Oxygen Sensor for Optimal Performance Review

It was a perfect addition to the wiring harness to allow for an OEM connection. Depending on your location, they can be very difficult to reach.

Perfect fit for my 02 Ram 1500 4.7L 4x4 with automatic transmission. The check engine light no longer lights up. Quick replacement once I removed the old one. The factory connector fits perfectly into the attached wiring harness of this sensor.

Smog test failed p0141 "Wait" no check engine light, bank 1 none. 2 heaters failed. Thank goodness it's ez to get there with a 7/8 key. Ohmed heater and it was open. I ordered this one from Revain, it fits perfectly and even has anti-seize lube in it. Smog test passed .2001 Dodge Dakota Quad Cab V8 4.7.

5 Stars Fits my 2002 Dodge Ram 1500 4.7L V8 4 Door SLT Used on a Bank One Gauge 2 to Little Cat. My pu has 3 of these, bought 2 on ebay last year, had to change the wire housings of the plugs as they were wrong, the second one didn't work, got stuck at 1 volt, this one was changed right inside. No more code and passed the smog, no problem, thanks

I read a lot on the internet before buying this O2 sensor. I've had trouble with aftermarket sensors in the past and wasted money. I usually buy Mopar parts from the dealer. Many forums have suggested this particular O2 sensor for my 4.7L Dodge Dakota 01. It worked great and the annoying check engine light didn't come on. It was also easy to install.
