How many O2 sensors does a 2009 Hyundai Santa Fe have?

How many O2 sensors does a 2009 Hyundai Santa Fe have?

There are four oxygen sensors on the Santa Fe (usually). There are 2 sensors “upstream” (on the manifold) and 2 “downstream” (one on each converter for the manifold).

Where is the oxygen sensor on a Hyundai Santa Fe?

The oxygen sensor is located in the exhaust manifold. It is threaded into the manifold and marked ‘heat protector’. The control circuit is integrated with the sensor wiring. If there’s a problem first check the sensor before proceeding to the control circuit. Is it difficult to replace both oxygen sensors on a Hyundai Santa Fe?

What happens if your oxygen sensor goes bad?

A wrong signal from a faulty sensor to the onboard computer can severely impact an engine. While most oxygen sensor problems involve replacement, self-replacing a sensor is often not as easy as it seems. If a sensor has to be replaced, consult an Expert who will provide step-by-step instructions on how best to proceed.

How many oxygen sensors does a Hyundai Tucson have?

Other important aspects to check is that there are no mechanical problems like exhaust or intake leaks and engine misfires. How many oxygen sensors does a Hyundai Tucson have and what would it cost to replace the lot? The Tucson has four oxygen sensors in all. Original replacements cost about $1250.

Can a lazy oxygen sensor cause a catalytic converter problem?

You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself. A technician can determine if the sensor is responding as it should.

What happens when the oxygen sensor goes bad in a Santa Fe?

More often than not, when an oxygen sensor in your Santa Fe goes bad, it will throw a diagnostic trouble code. There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are.

Can a faulty oxygen sensor cause poor gas mileage?

If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter. Many oxygen sensors are damaged by leaking oil or coolant.

Why do oxygen sensors need to be replaced?

Many oxygen sensors are damaged by leaking oil or coolant. If that is the case, the cause of that leak needs to be identified and repaired, or else the replacement oxygen sensor will be damaged as well. New vehicles require specific oxygen sensors, and not the universal sensors that were common prior to 1996.

Why does the Check Engine light come on on Santa Fe?

Oxygen sensors can change the way that your Santa Fe’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
