Yes, performance and fuel economy will suffer.
It screwed in to the exhaust manifold. To change it you unplug the sensor and unscrew it with an O2 sensor socket.
The oxygen sensor on a 98 Chevy K1500 truck is located in the exhaust manifolds. It monitors oxygen levels in the exhaust gases and allows the computer to make adjustments for optimal performance.
It is in the exhaust manifold next to the firewall.
combustion noise sensor signal use To reduce the emission and improve the performance by changing the ignition timing. When the engine is accelerated the timing can change, you get a pinging noise. It senses that and adjusts the timing to compensate. They didn't have this in older engines without electronic ignitions and you had adjust the distributer to find a happy medium setting. It really imporves performance and power. Its not the same as an exhaust sensor that reads the unburnt fuel level and adjusts the fuel to lean out the mix. The exhaust sensor is more for the emission controls.
When the TPS sensor is disconnected from the car in idle, there would be delayed acceleration.
Hey Mario==It will be close to the exhaust flange and on some cars it is in the exhaust manifold. GoodluckJoe
Code 0404 is the exhaust gas recirculation circuit range performance problem. Code 0405 is the exhaust gas recirculation sensor A circuit low.
That is the O2 sensor in the exhaust closest to the engine.
you do have an ( 02 ) sensor on the exhaust system
Oxygen sensor or lambda sensor is situated in the exhaust pipe in front of the catalyst. Disconnect from loom and unscrew with large spanner.
unplug it from wiring harness and unscrew the o2 sensor from the exhaust pipes, and reverse the process with the new one
Near the starter on the exhaust header. If it is 1990 it will be fun to break the rusty sensor out of the truck. good luck
