What can cause a false o2 sensor code?

Besides contamination, compression leaks or malfunctions can confuse the oxygen sensor, which leads to incomplete combustion causing high levels of oxygen in the exhaust system. This is also the case with a leaking exhaust manifold. Another source of oxygen sensor error codes can be the heater of the wideband.

What does the O2 sensor on a Honda Civic do?

The Civic’s computer uses the oxygen sensor to measure the amount of O2 gases in the exhaust. It uses this data to tune the engine on the fly. When there is no signal from this oxygen sensor, the engine will not be able to run at optimal efficiency, and you’ll get that annoying check engine light. P0134 affects Bank 1 Sensor 1.

Can you replace O2 sensor and still get check engine light on?

Replace O2 Sensor and still get Check Engine Light On. Replaced O2 Sensor and still get Check Engine Light On. 2 different shops did reads on my check engine light codes, I even paid $100 for one of them to do a full test of all sensors to identify which one was bad. Their diagnose was code P0141, oxygen sensor heater, o2 sensor had to be replaced.

What does no activity mean on Honda Civic?

P0134 is a relatively common OBDII trouble code. It’s generic, which means that it has the same meaning for any vehicle with OBDII. It means that the PCM/ECM is not detecting any activity from the sensor. The Civic’s computer uses the oxygen sensor to measure the amount of O2 gases in the exhaust.
