When did Honda start using heated oxygen sensors?
The second generation of heated oxygen sensors (since the mid-1990s): Every 100,000 miles (160,000 km). Find out how many Honda oxygen sensors your vehicle has. Some vehicles introduced two Bosch oxygen sensors on V6 and V8 engines in the late 1980s.
What does code p0141 on Honda oxygen sensor mean?
P0141 HONDA Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up.
How is the heated oxygen sensor heater controlled?
The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
How does the heater control module work on a Mazda?
The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow.
Why is my Honda O2 sensor heater not working?
Current amperage in the front heated oxygen sensor heater circuit is out of the normal range. (An improper voltage drop signal is sent to ECM through the front heated oxygen sensor heat

How is the O2 sensor heater circuit controlled?
The O 2 sensor’s heater circuit is controlled in one of two ways. First is the positively controlled type of circuit. If the O 2 sensor heater circuit’s negative wire goes directly to ground, look for a short-to-power problem. Usually the heater circuit in this case is controlled by a relay. Remove the relay and retest the circuit.
Is there test to check O2 sensor heater?
And in that respect, they’re fundamentally the same. One popular test is to check the amperage of the O 2 sensor’s heater circuit. This test confirms that the O 2 sensor’s heater itself is working and would lead you to believe that the vehicle is fixed.
Can a heater with an oxygen sensor fail?
Oxygen sensor heaters do fail. But there are other possible causes for a heater DTC. Before screwing in a new sensor, this simple test will determine whether everything else is in order. As vehicles grow older, there comes a point when the oxygen or air/fuel ratio sensor’s heater circuit will probably fail.

Where is the oxygen sensor located in a Honda Civic?
In 1996, a second generation of vehicle On-Board Diagnostic (OBD-II) computers were introduced in the United States and the use of two oxygen sensors was required. The Primary Oxygen (PHO2) sensor is placed between the catalytic converter and the exhaust system.
