Could be as simple as a popped fuse. Also check the wiring surrounding the sensor, could be exposed or frayed

upstream and downstream oxygen sensor heater voltages are too high, possible causes are
- bad o2 sensors
- shorted o2 wiring
- bad pcm
clear codes and determine if codes are hard(current)
if they are, unplug sensors, clear codes and re-scan to see if p0032 and p0038 appear.(there will be 2 to 4 other codes generated)if p0032 and p0038 are gone from the list, change both o2 sensors.
if p0032 and p0038 are still in the list, it is either wiring or pcm issue, use a meter to check for short from o2 connector to ground, with pcm unplugged..
Good luck, Rob

OBD2 P0032

Hi there:

P0032 - Oxygen (A/F) Sensor Heater Control Circuit High (Bank 1 Sensor 1)
A P0032 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2.



This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. The sensor detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the O2 sensor. Essentially this P0032 code means that the resistance of the heater circuit is higher than normal. In some cases, that resistance level must be higher than 10 A to trigger the DTC code.


Note, this code is very similar in nature to P0031, P0051, and P0052


Potential Symptoms:
Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate.


Causes: A P0032 DTC trouble code may be caused by one or more of the following:
A short in the heater circuit in the sensor
A failed O2 sensor heater
Wiring/connectors broken/frayed leading to sensor and/or relay
Failed PCM/ECM


Possible Solutions: To fix a P0032 DTC code, you'll need to do a proper diagnosis. To do that, you'll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to:


check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement)
check the ground circuit for continuity
measure the resistance of the heater circuit (done on the sensor itself)
measure the resistance and voltage of the wiring
Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is above 10 A.


With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #2 on bank 1.


Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There's also a chance that replacement parts for the P0032 code may also fall under a federal emissions warranty (check with your dealer to see if it's covered).


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.

Heater control circuit high, bank 1 sensor 1. Sounds like your O2 sensor in bank 1 in front of your convertor is bad.

Hi.

P0032 means HO2S Heater Control Circuit High (Bank 1 Sensor 1).

It means high impedance from O2 sensor, check wiring to sensor and replace the sensor.
Check O2 sensor located in bank 1 (cylinder 1 side- see here), and after the catalitic converter (there is also an O2 sensor before cat converter).

This means you have a problem with your oxygen sensor,or circuit.Bank1 sensor 1 is the O2 on the drivers side before the converter.Check for any burnt or broken wires,if ok,then check the sensor
