Recently my 1999 Civic Ex Manual transmission CEL came on after driving on the high way and the car continued to have this feeling as if the car would not be giving the engine enough gas and then it would start to slow down and then surge the engine with gas and it would buck and jerk. I scanned the engine and received PO132 O2 Circuit High Voltage (Bank 1, Sensor 1). I am hoping it might just be a faulty O2 sensor and a quick replacement. Any thoughts? maybe a bad fuel filter?? any help would be great.

 

The code is thrown because the primary O2 sensor is bad or the wire between the O2 sensor and ECU is bad. Fix this problem first. If the bucking persists, check the ignition system (plugs, wires, cap, rotor).

 

Does anyone know if Bosch O2 sensors are good? and how expensive are they usually? I am dealing with a private mechanic and he said it usually costs him about 180$ Canadian to buy a Bosch O2 sensor does this sound about right?

 

How does the price convert to U.S. dollars?

I haven't heard much enthusiasm for Bosch O2 sensors, although they are definitely less expensive than the Honda replacement part.

Search for online prices of the Bosch sensor and then compare them with the Honda part (better and more expensive) here:

Canadian dollars are worth about 94 US cents today, so the $180 Canadian is about $170 US. Simply go to google and enter "180 canadian dollar to dollar" and it will compute it for you.

 

Based on mk's price conversion, I think the mechanic may be over charging you. Buy your own and install it. It's a pretty straightforward job. Just purchase an inexpensive O2 sensor wrench or socket.

 

is it just a straight forward unscrew the old o2 sensor and disconnect it and screw in the new one and connect it and your done?

 

Yes. But the old one is sometimes quite stuck and hard to unscrew.

Also after replacing the sensor, reset the ECU to clear the code. Hopefully it was caused by the old one being bad and it won't reoccur.

 

also if bosch arent good sensors what kind are? The stock sensors are the best??

 

I have a 2000 EX that has the exhaust system shown in the first diagram below. Removal of the sensor from the exhaust pipe is shown in the second diagram below (see B16a even though my engine is D16Y8). The primary O2 sensor is very accessible underneath the car when the front end is lifted on jack stands. Let me know whether your O2 sensor is instead located in the exhaust manifold.

You may want to spray a little penetrating oil around the threads of the old sensor and let it sit for 30 minutes prior to attempting removal with an O2 sensor wrench or socket. Take your time and don't break anything. After removal, wipe away all oil around the plug hole and then install new one.
