Those tell the computer it can't believe whatever readings it might get. P0138 is 02 circuit high voltage Bank 1, sensor 2. It consists of the exhaust manifold, converters, pipes and mufflers. For optimum catalyst operation, the air fuel mixture air-fuel ratio must be maintained near the ideal stoichiometric ratio. Slid the mesh covering back to check the actual harness splice points and to look for damaged wires. What are the symptoms of code P0038? You should have less than 1 Ω resistance end to end and more than 10 kΩ between them and to ground.

Two types used are manual or automatic. If the sensor was replaced and the wiring is in good shape, the code scanner should indicate a reading that falls close to the mid-point between a rich-, and lean running condition. Some aftermarket fuel and oil additives contain silicone-based compounds that can cause deposits to form on spark plugs and oxygen sensors. Start by looking for a corroded terminal in the sensor's connector or a terminal that got stretched or pushed out of the plug body. This could cause fouling of the O2 sensor. That sounds loke a great idea ill let you know friday late afternoon.

P0138: O2 Oxygen Sensor Circuit High Voltage Bank 1, Sensor 2

02 sensor circuit high voltage bank 1 sensor 2

In practical terms, this means that sensor 1 measures the amount of oxygen in the exhaust stream as a function of the combustion process before it enters the catalytic converter, while sensor 2 measures how well the converter s copes with cleaning up the exhaust stream. Heating the element electrically brings the sensors into operation much sooner than would have been the case if the sensors were heated by the exhaust stream; by bringing the sensors into operation sooner, emissions are reduced significantly. Here's your Oxygen sensor codes. Step 3 If the code persists, perform reference, continuity, and resistance tests on all associated wiring. . This is due to the fact that O2 sensors are under the chassis where they are subject to punishment from road debris, and they are subjected to a lot of exhaust heat. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia.

Ensure that the gaskets are installed correctly. A variation of around 100-, to 200 millivolts to either side of the mid-point is acceptable, but the reading should remain constant if the engine speed does not change. The specific code that is being set changes the way you must go about diagnosing and repairing the problem. Check the oxygen sensors for damage. Another repair would be to replace the wiring or connection for Bank 1, Sensor 2. In some cases, there can be other symptoms as well. If you have anything that you would like to add, please feel free to leave a comment below.

A leaking fuel injector could possibly be another cause. What repairs can fix the P0138 code? That will help you narrow down the location of the problem. Check for continuity on the two lines. Ground the plug at a good ground location on the engine. Do a visual check of the connections as well as using a Volt Ohm meter for wire connections. The automobile consist of: Powertrain: 1. The only way to set this code is to have a break in the sensor's ground wire or the signal voltage wire is shorted to the 12 volt heater wire for that sensor.

Resistance specification: 11 - 16 ohms at 20°C 68°F. It consists of water pump, hoses, radiator, thermostat, cooling fan and coolant recovery tank. Look for damaged, shorted, burnt, or broken wiring and connectors. So I can listen for the noise, as with the speaker and mirror I will have with it as collage semester over in couple weeks. It also divides torque between the wheels. But, like anything that causes the service engine soon light to come on it is a good idea to have it fixed as soon as possible. All circuits tested to be properly functioning so the o2 sensor was replaced.

The numbers below refer to the step numbers on the diagnostic table. The Engine Control Module adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. Exhaust leaks can contaminate the atmospheric air used by oxygen sensors, which contamination can result in inaccurate readings. Crank the engine and check for spark. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Those codes prove the sensor is working; it's just reporting what it sees.

P0132 trouble code definition 02 Sensor Circuit High Voltage Bank 1 Sensor 1 What the P0132 code means When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor. If it is the cat bad they are under federal warranty for 80k or 8 years. O2 Sensors are the final checkpoint in the engine management system. Suspension: Purpose is to provide stability and handling while also providing comfort to the ride. All these symptoms should prompt you to want to investigate the problem further.

Other codes, like 138, report a defective condition in the circuitry. Manufacturers constantly strive to build their vehicles to meet tougher emission standards each year. The plastic portion of the sensor has arrows cast into it indicating proper air flow direction. The ticking can be caused by an exhaust leak. The P0132 trouble code is not widely considered a serious one. Since I have otherwise had no other problems, and no other codes present how likely is it to be just a faulty O2 sensor? It consists of master cylinder, brake booster vacuum or hydraulic , calipers, drums, pads and rotors.

It consists of a ring and pinion gear, carrier, bearings, crush sleeve and axle shafts. Remember rated this help, good luck. While the symptoms of code P0038 are much the same on all vehicles, the severity of one or more symptoms may differ from vehicle to vehicle. If full of fuel, inspect the canister control and hoses. Water entry and corrosion are common faults. If the light comes on, even for a second, you know that you have a short circuit causing the P0138 trouble code. In this case it was an o2 sensor.
