What causes the p0059 OBD-II trouble code?
When this trouble code sets it means there is some sort of malfunction in the heater circuit for the bank 2 sensor 1 oxygen sensor. This most likely means that the heater is non-operational. What causes the P0059 code?
How to test an oxygen sensor with DTC p0135?
If you do find that the oxygen sensor’s heater is getting both power and Ground, then the next step, is to measure the resistance (with a multimeter) of the heater element inside the oxygen (O2) sensor to see if it’s fried or not. As you can see, testing DTC’s P0135 and/or P0155 is not hard to do at all.
When does p0059 detect that the resistance is incorrect?
When it detects that the resistance is incorrect P0059 can set for the bank 2 sensor 1 oxygen sensor. There could be a problem with the wiring for the circuit or the oxygen sensor may have failed internally causing the resistance for the circuit to be incorrect.
Where are the O2 sensors located in an oxygen heater?
Before you start testing/troubleshooting codes P0135 and/or P0155, I recommend that you take a look at the following oxygen sensor tutorial: Testing P0135, P0141, P0155, P0161 O2 Heater Performance Problem . Symptoms Of A bad oxygen sensor heater element. Where are the O2 sensors located? What tools do I need?
What does p0059 mean on an O2 sensor heater?
Since a P0059 code means that the upstream O2 sensor heater is basically inoperable, it should be addressed at your earliest convenience. Symptoms of a this engine code may include:
What does diagnostic trouble code p0059 mean?
The definition of diagnostic trouble code p0059 is that the resistance for the heater circuit of bank 2 sensor 1 oxygen sensor is not correct. When this trouble code sets it means there is some sort of malfunction in the heater circuit for the bank 2 sensor 1 oxygen sensor. This most likely means that the heater is non-operational.
When to use the p0059 heater resistance bank?
A P0059 will be stored if O2 sensor heater voltage varies from that of the battery, due to a resistance issue. Connect the DVOM test leads to the sensor ground and battery voltage signal wires in order to monitor live data from the O2 sensor. You may also be use the DVOM to check resistance of the O2 sensor in question.
What causes p0059 to set on Bank 2?
There could be corrosion or damage to the terminals that is causing a poor connection and causing P0059 to set. By far, the most common “mistake” is simply replacing the bank 2 sensor 1 oxygen sensor without performing and diagnostics at all. This happens a lot because the vast majority of the time it is the sensor itself that has failed.
