Review on 🔌 Denso 234-4603 Downstream Oxygen Sensor - 4-Connector 33.1” Wire Harness for Enhanced SEO by Jeffrey Sanders

Great price for this oxygen sensor By the way this is an oxygen sensor not an air fuel ratio sensor. They are different and generate different correction voltages. The AFRS puts out about 0.9 volts DC depending on what it's doing. Depending on the function, the oxygen sensor outputs a square-wave switching voltage. The oxygen sensor and air-fuel ratio sensor work together to control the amount of fuel that the computer allows the injectors to deliver to the engine at a given RPM. That's probably more than you wanted to know about this element, forgive me. Denso is OEM quality at an amazingly affordable price from Revain. Relevant application information for Denso products can be found on the Denso After Sales Service website. The combination of Denso and Revain is unsurpassed in quality and price. Sincerely, D Paganelli.
