P0032"Heated O2 Sensor Circuit High Bank 1 Sensor 1" The ECU detected a high resistance condition in the heater element circuit for the pre-catalytic converter sensor.Probably just need to replace the sensor,but you can check for voltage across two of the wires(see your wiring diagram).
Hi there: Are you buy same or OE part replacement according with the Hyundai part number catalogue? This is important. Keep in midn that you need reset or delete all previous code stored in the car computer.
DTC P0131 - Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1) Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
A code P0131 may mean that one or more of the following has happened: - Faulty o2 oxygen sensor - Short to voltage on O2 signal circuit - High resistance or open on O2 signal circuit
Possible Solutions: - Replace faulty sensor - Repair short, open, or high resistance on o2 signal circuit
A code P0135 may mean that one or more of the following has happened: - O2 Heater element resistance is high - Internal short or open in the heater element - O2 heater circuit wiring high resistance - open or short to ground in the wiring harness
Possible Solutions Repair short or open or high resistance in wiring harness or harness connectors Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
you have 4 O2 sensors, bank one is the front cylinders ( close to the readiator ) there is 2 bank 1 O2 sensors one infront of the catalitic convertor ( bank 1 sensor 1 ) and one after the convertor ( bank 1 sensor 2 ) the same on the back cylinders they are bank two sensors 1 & 2 i will try to post the location of the wiring plugins if you find the plugs then you can folow the wiring to the sensor....good luck
low voltage o2 sensor bank 1 sensor 1 the computer registered a fault that the o2 sensor had lasted over 2 minutes problem faulty o2 sensor --short in sensor/wiring--short in wiring circuit sensor 1 is the sensor before the cat converter
P2251 L.O2 reference circuit(-) open-Sensor 1. This code is showing a problem on the reference voltage of the upper O2 sensor. It might be sensor or the wiring. P0304 Cyl.number 4 Misfire detected. This code is showing 4th.cylinder is or has been missing. Second code might be set by first code.O2 sensor problem needs to be corrected first.
