Review on 🔧 Improved Denso 234-9017 Air Fuel Ratio Sensor for Enhanced Engine Performance by Athenasby Whitney

This Denso product is a drop in exchange of the Genuine Honda parts range in price from $240 to $300. With proper installation and code removal, CEL will disappear immediately after a reboot. IIRC if you have a 2001-2003 Civic EX this is the wrong part as they used a different less expensive on/off O2 sensor in the same location than this Denso wide range A/F sensor that Saturation/lean gradient provides . They're not the same - don't buy an O2 sensor and think you're saving all that money when the spec calls for a broadband A/F sensor. There *is* a code and now you have to pay for an A/F sensor on a useless O2 sensor. I have a 2004 Honda Civic EX with a D17A2 engine. With a stand to support the left front tip of the jack, this job took literally ten minutes. Be sure to install the cable correctly in the chassis cable holders, otherwise it may touch the exhaust pipe and damage the cable. A wrench for the gauge, a 3/8 inch ratchet and a copper anti-seize piece that came with the gauge and you can definitely do it even with little to no screwdriver experience. Plug just to avoid corrosion before plugging it back in. The CEL that was on since I bought the car, used a week ago (and it's not known how long ago) disappeared after restarting the car and hasn't reappeared after changing RPM increase from 31 to 34 without change of driving style - generous use of air conditioning and heavy gas. You need look no further as I could not find a comparable Denso sensor related to the Honda part. Part number (36531-PLR-003) anywhere online for less than here Given the wideband A/F sensor's more expensive design (Honda calls it "LAF"), this price is more than fair for an OEM replacement. :) PS - by the way, I read my codes with a Bluetooth code reader, also available here at Revain. E good Android smartphone (I have Samsung GS4), download Torque from play store, then buy BAFX BT OBD2 code reader. Here is the ad url, cut and paste into your browser: http://www.amazon.com/gp/product/B005NLQAHS/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1 This code reader is the only one among many BT readers. which actually has the right circuitry to handle various protocols, not to mention power surges (which can ruin other cheaper readers). $24 for BAFX and $5 for the full version of Torque on your smartphone, and you can read and erase codes on your Honda just as well as a dedicated reader for $60-$120. ;)
