The present invention relates to a system and method for determining the resistance of the oxygen sensor heater. 一种发动机控制模块,包括排气加热模块,温度确定模块和电阻测量模块. An engine control module, including exhaust heating module, the temperature determination module and resistance measurement ...
The method involves turning off a heater of an oxygen sensor when the engine is turned off and allowing the sensor to cool. While the sensor cools, the sensor resistance is measured by means of a large pull-up resistor and a small pull-up resistor, with the small resistor being switched ...
An oxygen sensor having a bar-shaped heater inserted in an elongate bore formed in a tubular solid electrolyte body which has porous platinum electrodes on its inner and outer surfaces and which is supported by a housing such that its closed end portion is exposed to exhaust gas and such that...

On some Toyota vehicles this code is triggered when the resistance of the heater circuit is above 10 A.With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #2 on bank 1.Please keep in mind that OEM (original equipment) replacement sensors are ...
4) HEGO Heated Exhaust Gas Oxygen Sensor 加热尾气含氧量传感器 5) thermal gas pressure microsensor 微加热式微气压传感器 1. Three types of test circuits, including constant temperature circuit, constant power circuit and constant bias circuit were designed according to resistance of the heater inthermal...
The invention relates to various oxygen sensors for use in μ probes, based on the fact that it is possible to verify a negligible temperature dependence of the electrical resistance of the sensor using complex metal oxides in conjunction with suitable amounts of dopant being added in order to ...
PURPOSE:To enhance durability of an oxygen sensor by making each of the primary particles of a metal oxide spherical in an oxygen sensor which has a sensing portion made from the metal oxide and which senses changes in oxygen gas partial pressure from changes in the electrical resistance value ...
