Replace the fuel injector if it is leaking. Need help with a P0138 code? In those cases there is always a backup strategy that lets the computer make fuel metering and ignition timing decisions based on other factors. Their overall purpose is to measure the amount of air in the while the exhaust gases are coming out of the engine. I am a Navy guy and trying to fix my 2001 Dakota quadcab 4x4 5. Not though that, a post-catalyst oxygen sensor normally switches fewer times and slower than front pre-cat O2 sensors. If it's normal, you have an intermittent problem that isn't currently acting up. But that car needs to have the wiring harnesses ohmed out in the suspect O2 sensor circuits to make sure you don't have a wiring problem first.
What are the symptoms of code P0138? This oxygen sensor is located behind the catalytic converter. Those tell the computer it can't believe whatever readings it might get. The Engine Computer will respond by adding more fuel but there will still be that extra oxygen there. What causes the P0158 code? The P0158 trouble code is considered serious if it is causing the car to stall out. How does a mechanic diagnose the P0138 code? 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.
Feb 29, 2012 P0132 is O2 sensor High circuit sensor voltage sensor 1 bank1, What this mean is either you 02 sensor on bank1 or where cylinder 1 is located is disconnected internally or extenally you will need to inspect the harness for any disconnection if connection is good then you will need a new 02 sensor Nov 03, 2011. If the sensor has a problem it will set a new code for bank 2. Here are some of the most common. Iights, fans, compressors, accessories at lower engine speed draw down the battery, and this is normal and okay. What causes the P0138 code? The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Water entry and corrosion are common faults.
That can draw in outside air and the oxygen will be detected as a lean condition. Don't mess with them until the other issues are resolved. Guess I need 40 drive cycles to reset computer. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. If it is the cat bad they are under federal warranty for 80k or 8 years. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Under normal conditions the heated oxygen sensor 3 is not used for engine control operation.
Check the oxygen sensors for damage. Do the plugs and wires last. The ticking can be caused by an exhaust leak. Wifes gona help me sat. There's a capacitor in there that is likely open. How serious is the P0138 code? From the heater positive to both sides of the sensor circuit should measure over 10 kΩ. You should probably replace them and maybe run a compression test while you're at it.
Be sure that the water is up in the battery and all connections are clean. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. السلام عليكم عندي مشكله في الاكسجين سنسر الي هوا p0138 معطيني انه جهد السنسر عالي مع اني غيرت السنسر وعملت فحص شامل للاسلاك ولاكن التشك انجين ما رضى يختفي عندي مع انه الكهرباء تدخل بشكل سليم وحتا المكينك مستغرب ولحد الحين لا زلات المشكله عندي يعطيني في الكمبيوتر اكسجين سنسر بنك ١ سنسر ٢ ونوع السياره كامري ٢٠٠٧ xli v6اتمنى الافاده اذا ما عليكم امر وتقبلو مروري. Other vehicles may be similar. Definition The O2 Oxygen Sensor Circuit High Voltage Bank 1, Sensor 2 is normally located in the catalytic converter, before the muffler, in the exhaust system.
. If you get no response, suspect a sensor or circuit fault. If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. The Engine Control Module adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. Sorry havent gotten back computer broke. The engine control unit is the computer which regularly monitors and communicates with these sensors. Depending on the vehicle, this voltage threshold may be different, so check your repair manual to be sure.
Each O2 sensor has four wires going into it. Electrical Connection Problems Check for damage to exhaust pipes and catalytic converter. Unfortunately, due to inconsistencies in engine operation, air and fuel temperature, fuel composition, and a number of other factors, exhaust chemistry can be far from ideal. 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. There is no fix that anyone can tell you without being able to run circuit tests on the car.
You'll have to chisel it out of the protective glop to replace it, or you can bypass it with a jumper wire. What are the common causes of code P0138? You will need to check with your dealer to confirm that. This problem should be addressed as soon as possible to avoid drivability issues. How do you troubleshoot code P0152? First, to answer kev2's question, the sensor is set to be delivered middle of next week I am told from my sources. There are separate codes for each sensor - bank 1 and bank 2, sensor 1 forward and sensor 2 aft. I appreciate all the information you have given me.
These inconsistent readings are often the reason to believe the circuit is losing voltage or ground into the O2 Sensor circuit. Sometimes it would rev a little but then go back to a very low lopey idle. If the catalyst is the problem, replace the catalytic converter. Sometimes they are thrown when there is an issue with the wiring or grounding. Check the oxygen sensors for damage. Bank one is the engine side with cylinder 1 plug wire 1 and bank two will be the other side. Bank 2, sensor 1 and the bank 2, sensor 2 O2's are in the same positions except they are on bank 2 of the engine.
