SOURCE: My engine light came on. error codes show P2195 and P1166

The fuel pump is vapor locking, common problem in high temp/altitude states. Call the dealer and see if campaign t-13 applies to your car, if the car was originally sold in a low altitude state, it won't apply. I recommend the fuel pump be replaced with updated fuel pump sub assy.

It sounds like your car is running rich. This could cause the catalytic converter to overheat and melt, blocking the exhaust, and killing your power. Have all of your emissions and fuel systems checked out, and make sure you aren't leaking any vacuum. Don't replace your cat before you find the problem.

I have an 04 Hyundai Elantra GT that throws a OBD2 code p2195 and p1166. What do I do to fix these error codes? And is it as simple as changing the Upstream O2 sensor? Thank you


Probly not..sensors should only b replacd if heating element bad. Changing other items must b done w caution unless theyr cheap. A scan w a vehicle specific or factorytool will direct u whats occuring. Only honest private shops havthem. Partstore scanners dont suffice

My check engine light came on. I found out the engine code is P1166 and P1167. Which oxygen sensor do I change, upstream or downstream, or both??


Start by changine the one closest to the engine. Probably in the exhaust manifold right in the engine bay. Recommend you buy OEM, as I've heard of people having issues with aftermarket sensors.
There's also a fuse for the heater circuit in the O2 sensors that could be blown, but I'd bet it's just a bad sensor.

Have had 02 sensor changed and check engine lite still comes on, is there more than 1 - 02 sensor in my 2002 Hyundai Accent?


When you get any code,it does not tell you anything is wrong or what to replace

You use the code to diagnose the part of the system,that set the code

Most likely cause for an O2 Code, is a vacuum leak,which drives the sensor lean, and it goes out of range. Thus the code is set (Education is the Key )

You have at least two O2 sensors for every single exhaust,four or more for dual exhaust.

Your current code may be a new problem

I have a 2002 kia rio the code that came up is p1166 how do i fix


P1166. Primary HO2S (No. 1) Heater System Electrical.

Replace O2 sensor. Iif it smells rich then you are getting too much fuel. You may have a problem with the fuel pressure regulator or a leaking fuel injector. This can also be caused by bad oxygen sensors.

Hops helps (remember to rate this answer).

It shows that code p1166 oxygen sensor has been changed and code keeps showing,emissions high I really dont know what else to do, we also try with another ECU and still turn the service engine light.


It showing you this fault, but sounds like your car is putting off out too much fuel mixture. Check your PCV valve along with the other components that recirculate the emissions.
