The sweet smell is the motor burning off the residual coolant on the components that got sprayed with coolant.if the car got overheated enough it may have damaged the head gasket and is now burning oil due to the over heating.or there is a mechanical problem due to the overheating(ring problem,valve problem,etc.)if its burning oil then it can cause an 02 problem as the sensor will get coated with what ever is coming out of the exhaust.the heat sensor is part of the 02 sensor that warms the sensor up so the computer will go into closed loop sooner and help with fuel mileage.

Thats why you dont take advice from ottozone. First you may really have had an oxygen sensor problem, then you bought one from ottozone, ( who brag about how cheap their parts are) then you put in another cheap sensor. Have your car looked at by well equipped repair shop thats not trying to sell you car parts.

My check engine light is blinking at me and the car accelerates very slowly from 0-30mph & between RPM 1-2 & makes a noise as if the car is coughing???


This is either a clogged catalytic convertor or a failed O2 sensor or both. A good muffler shop can fix this easily.
Dont replace the o2 sensor until you have verified that the catalytic convertor is good, or you may burn it out.
A quick way to diagnose a clogged cat is to check exhaust pressure and heat from your tailpipe. Restricted flow = Heat plus steam plus low pressure. Sometimes there is no steam.

Riding rough what do i change with these codes po171, po174, po300


171 and 174 are lean mixture codes, 300 is a random misfire (any cylinder). Check for a vacuum leak, listen for a hissing noise with engine idling.

Need to locate o2 sensor location bank 1 sensor 2. I replaced the one on top nearest the radiator, but still getting o2 error code for a different one. Need to find its location on a Hyundai Accent 2000


You need to check two things.

First, there is a heat shield on top of the front of the motor where the o2 sensor you already replaced is. It's got (4) 12mm bolts. Remove it and check the exhaust manifold (big thing you put the o2 sensor into) for cracks. If there are any cracks, you'll get o2 sensor codes. Replace the manifold.

Second, if the manifold is fine start the car and listen to the exhaust pipe under the engine for leaks. Or if you already know the exhaust is loud... that's gonna do it too. A leaking exhaust pipe on an Accent will set secondary o2 sensor codes.

SHOULD you try to change it yourself, you will need a 7/8" wrench, and a new o2 sensor, or flex pipe, or manifold depending on what's broke. Do NOT touch the tip of the new or old o2 sensor to ANYTHING when you take it out or install it or it will be ruined permanently. Run the car until it's at it's normal operating temperature. Raise the vehicle, and take the o2 sensor out of the car (see below to understand which one) using the 7/8" wrench or if you got fancy and bought an 02 sensor tool... use it.

Replace whatever parts are bad (manifold or pipe) or just replace the sensor you need. Then restart the car and take it to a parts store and have them clear the code. The code (and check engine light) won't return right away, it usually takes a few days. If you did everything right you should be good. If not, it's not a terribly expensive job to have done and by now you should be able to explain to them what's wrong based on what you found when you looked at the car. Just tell them everything you checked and what you saw.

Education: I'm not sure where that half baked answer about o2 sensor 1 being near cylinder one came from but here's the real deal.

Sensor 1 is always BEFORE the catalytic converter
Sensor 2 is always AFTER the catalytic converter

Bank 1 and Bank 2 refer to which SIDE of the exhaust on 6 and 8 cylinder engines. Bank 1 is usually left side, Bank 2 is usually right side.

So... O2 sensor B1S1 refers to the O2 sensor BEFORE the converter on the LEFT side of the motor.
