How does an ozone sensor work in zero air?
In zero air, little or no electron flow occurs. As the presence of ozone increases, the electrical signal increases proportionally. The sensor interprets this signal and outputs the ozone concentration in ppm (parts per million) or ppb (parts per billion).
How do you replace an oxygen sensor in an exhaust manifold?
Using an oxygen sensor socket, remove oxygen sensor from exhaust manifold. Lightly coat new oxygen sensor thread with anti-seize compound. Install new oxygen sensor and tighten to 50Nm (37 ft-lb). Then reroute wiring harness and connect electrical connector. Repeat if replacing both sensors.
How is ozone gas measured in an EC sensor?
In an electrochemical (EC) sensor, ozone gas diffuses across a porous membrane into a cell containing electrolyte and electrodes. When ozone comes into contact with the electrolyte, a change in electrochemical potential occurs between the electrodes causing electrons to flow. In zero air, little or no electron flow occurs.
How are heated metal oxide sensors sensitive to ozone?
In heated metal oxide sensors a metal substrate is heated which allows it to become very sensitive to ozone gas. An electrical current passes through the metal substrate. The resistance of the current changes according to the mount of gas present.
What kind of radiator does direct ozone reduction?
This article explains a little more about the ozone reduction radiators noted as PREMAIR. http://www.autoserviceprofessional.com/article/92552/mitsubishi-dor-radiator
Is there a smog sensor in the radiator?
The sensor that is incorporated into the radiator, if tampered with, sends a encrypted code and the engine light stays on. Cannot smog, no sale. Mitsubishi was notified many times but no solution has been presented. Wanted to make all aware of an issue with a 2007 Mitsubishi Outlander I am trying to purchase from a private dealer.
Can a Dor sensor be replaced in a radiator?
With some research, come to find out that the radiator is a DOR and must be replaced with a DOR. The sensor that is incorporated into the radiator, if tampered with, sends an encrypted code and the engine light stays on. Cannot smog, no sale.
