How many O2 sensors does a 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).

How do I fix code P0158?

What repairs can fix the P0158 code?

1. Replace the rear oxygen sensor.
2. Repair any oxygen sensor wires that have shorted out, are broken or exposed.
3. Make necessary repairs to remedy the excessive fuel pressure.
4. Replace engine coolant temperature sensor if it is necessary.

What causes a P0160 code?

Trouble code P0160 sets when the engine management computer does not detect any activity on the oxygen sensor circuit for bank 2 sensor 2. Generally, an oxygen sensor’s voltage will vary up and down. The second sensor varies slower and the voltage variance is smaller due to the catalyst in the exhaust.

How many catalytic converters are in a 2008 Hyundai Santa Fe?

It appears that you have 2 converters – one at each exhaust manifold.

What is p1128 code?

Code p1128 refers to “Closed loop fueling not achieved”, meaning that for some reason the engine is not reaching a state where it is able to run using the information from the engine sensors.

What does the p0116 code on a Hyundai ECT sensor mean?

The PCM expects to see slow resistance changes on the ECT signal circuit. If it sees a quick change in voltage that isn’t consistent with an engine warming up, this P0116 Hyundai code will set. Or if it sees a lack of change in ECT signal, this code may set. If there are any other ECT sensor codes, diagnose them first.

What is the p0133 code on a Hyundai Santa Fe?

The code P 0133 is for the O2 sensor bank 1 sensor 1 slow response. So many of these cars have the same problem. The sensors have been replaced, fuel caps, intake manifold gaskets, computers replaced, etc. and nothing seems to solve the problem. Hyundai seems to have no answer, other than trade it in for a new Santa Fe.

What does code P0158 and p0160 mean on a Hyundai Sonata?

I have a 2006 Hyundai Sonata 3.3L that was throwing a P0158 and a P0160 code. My code reader said it was for the O2 sensor in the Bank 2 Sensor 2 position. P0158 is high voltage, while P0160 is no activity. I swapped out the B2S2 sensor and reset the code via the too…

How do I read a fault code on a Hyundai?

You will need a Hyundai multi-system OBD-2 scanner to read Hyundai-specific fault codes. Follow these steps to retrieve the fault code from your Hyundai. Turn the ignition off.
