The O2 sensor is located on the exhaust pipes.Be sure you change out the right one as some vehicles will have 4 of them others maybe 3 make sure you are replacing the right one.

Check engine light comes on for 2004 Hyundai Sante Fe. O2 sensor was replaced but still has the problem. Does the EGR manifold tend to get clogged up on the Sante Fe? I fixed a Honda Civic check engine...


First of all, why was the O2 snsr replaced?... Check Engine light? What DTC (diagnostic trouble code) did you find stored in the ECU (Engine Control Unit)? The drivability you seem to be describing can have multiple causes -- faulty sensors, malfunctioning computer, clogged catalytic converter, leaky injectors, vacuum leaks, etc.

Ok... this is gonna take some time. The 04 Santa Fe came with 3 (three) different/possible engines -- the 4 Cylinder 2.4 lit, the 2.7 V6, and the 3.5 V6. Only the 2.4 (4 cyl) and the 3.5 V6 are equipped with EGR. The 2.7 does NOT have EGR. To answer part of your question, the EGR system on the 4 Cyl is known to develop restriction(s) in the EGR port (from the # 4 cylinder exhaust port to the EGR valve at the intake manifold). This port travels through the head (front to rear, i.e., Left to Right when viewing the engine from the transmission end). This port cannot be seen at the # 4 cylinder exhaust port unless you remove the exhaust manifold.

It would be very helpful if you could provide more detailed/specific information regarding the drivability issue & what/which codes were found related to the Check Engine light.

Check engine light is on took to auto zone they gave me a code that said P1166


Hello there:
P1167 and P1166 codes relate to the primary O2 sensor heater malfunction.
there are two different O2 sensors, a "universal" sensor from Autozone and a supposedly OEM sensor from O'Reilly's. Both of them may cause the car to throw a p1166 or P1167 code and run rough. so i highly recommend getting a O2 sensor from Honda, and this will fix the problem .
It turns out that none of the aftermarket probes from Bosch or Denso will work on a ULEV (F23A4) 4 cyl. engine. Honda had different part number probes for the normal VTEC 4 cyl. and the ULEV Vtec engine and the probes look different and have different length cables. The computers at O'Reilly's, Autozone, or NAPA made no distinction between these two engine types.

2001 Sante Fe O2 sensors


On a single exhaust there are two. One before the catalytic converter and one after it. You need special socket to remove them. O2 sensor have four wires. Two is for the heater. O2 sensor have heater inside them thats why they are called heated O2 sensors. The other two is for the actually leads that sense the amount of oxygen in the exhaust gas.
When the heating element in the O2 sensor is burnt out it would have a code related to the heater circuit malfunction. An old O2 sensor would have a code about slow response such as P0133 for example. Bad connection somewhere may indicate no activity.etc. O2 sensor are good for about 2 years then they start giving you problem.
