When resistance is out of specifications with this trouble code set. She hit the pole on the drivers' side from the front of the wheel well flare to the gas filler door. What repairs can fix the P0060 code? Speaking of grounds, if they don't have dedicated ground wires, I'd make sure they're grounding well. Many thanks for your comments. Common mistakes when diagnosing the P0161 code The most common mistake is not performing any diagnostics at all and simply replacing the bank 2 sensor 2 oxygen sensor.
Some of the other causes of P0161 are listed below. If it is the cat bad they are under federal warranty for 80k or 8 years. She hit the pole on the drivers' side from the front of the wheel well flare to the gas filler door. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. I would check the wires for continuity first. Now to just get my tune back in so I can make that annoying abs and brake light turn off, and get some balls back in the truck! By consulting the wiring diagram for you vehicle, determine which pin on the connector is power and which is ground. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter.
Can someone provide the exact location of this sensor. How do you troubleshoot code P0161? They are relatively affordable at Autozone or. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. Vortec 485360 wiring harness info unmodified 01 truck harness labels for trans cam sensor oxgyen sensor range sensor. Typical O2 sensor heater circuit and connectors Courtesy: alldata.
In this case study, we are only concerned with the heater circuit. So, I'm a slow learner, but all is well now. One lead would probably need to be extended with a length of good wire to reach both ends of the harness. Will check the fuse but what else is left to correct or get that the little light off. For this reason, downstream O2 sensors are known as catalyst monitors.
Gm 53l liter v8 vortec lmg engine info power specs wiki gm gm 53l liter v8 vortec lmg engine info power specs wiki gm authority. The P0161 trouble code is caused by an incorrect amount of resistance in the heater circuit. Sensor 1 on Bank 2 or Sensor 2 on Bank 2? This code can only be caused by problems in O2 sensor heater circuit, or by the sensor itself. Need help with a P0060 code? What are the symptoms of the P0161 code? The only thing you will notice is an illuminated check engine light on your dashboard. It is used to determine the concentration of oxygen in the exhaust gas.
Set your meter to the ohms setting. Also sometimes there is a pcm reflash for the pro. The information contained on this site is presented for informational purposes only. A low voltage reading from the sensor would mean that side is very lean if the sensor is working and the sensor in front of the catalytic converter shows the same readings. It does so by checking the oxygen content of the exhaust after it leaves the converter.

However, from time to time there can be an issue with the wiring harness being damaged in some way.
Bank 2 is the bank that is farther back than the other when looking at eng from the front you will see that one cyl head is farther forward closer to radiator than the other. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. I'd repeat for the other O2's wire. The service manual for your vehicle has a resistance specification for a good sensor. An engine will usually take about 15 minutes of running to heat the oxygen sensor up to its required hot temperature. If the oxygen sensor is malfunctioning the vehicle will usually emit higher amounts of emissions which is worse for the environment.

An accurate oxygen sensor reading is needed immediately after the engine is running. This code can only be caused by problems in O2 sensor heater circuit, or by the sensor itself. Usually a will fix this particular code. Set your meter to the ohms setting.
The purpose of the heated element in the oxygen sensor is to quickly bring it up to normal operating temperature after your Sierra has been started. I really do not want to change out more than one. Modern vehicles use both an upstream and downstream oxygen sensor. In this case study, we are only concerned with the heater circuit. I'd use a meter that beeps for continuity. A code P0137 may mean that one or more of the following has happened: Faulty o2 sensor Exhaust leak near the rear sensor Plugged catalyst Short to voltage on O2 signal circuit High resistance or open on O2 signal circuit Possible Solutions… Replace faulty sensor Repair exhaust leak near the rear sensor Check for restriction in catalyst and replace as necessary Repair short, open, or high resistance on o2 signal circuit Mar 08, 2010 the bank 2 sensor2 is used to check that your catylitic converter is working on that side of the exhaust. The P0161 trouble code is not the most serious of fault codes.
