Since the voltage is high, the oxygen sensor is seeing a constantly rich fuel condition in the exhaust. Nevertheless, a dead sensor can cause this problem, but it needs logical diagnosis. When conducting a repair for this error code, the O2 sensor set and propane tank are needed to remove the O2 sensor if it is difficult to reach or has ceased in the exhaust. I would start by looking at the wires between the door hinges to see if any are frayed and touching. A leaking fuel injector could possibly be another cause. This includes keeping an eye on anything that might cause emissions to increase. The mirror problem is unusual.
The part is replaced, but the problem persists. Once again than you very much. Is the harness wire in good condition? Ho2S 2 signal is less active than signal produced by front oxygen sensor. What repairs can fix the P0138 code? Therefore, if the output voltage is low, use a jumper wire to connect the terminal No. It can be assumed that this malfunction is intermittent. Conversely, when the air-fuel ratio is richer than the stoichiometric air-fuel level, the oxygen concentration in the exhaust gas becomes lean. I whipped out my Innova 3100i that I keep at home and pulled a code P0131.
Check harness connector C-44 at heated oxygen sensor front and harness connector D-40 at heated oxygen sensor rear for damage. This happens because the flip-flopping of the fuel mixture is slowed down which reduces converter efficiency. What causes the P0138 code? If the catalyst is the problem, replace the catalytic converter. If the O2 Sensor body has a chalky appearance, this indicates lag between phases and should be replaced. Sensor Diagnosis O2 sensors are amazingly rugged considering the operating environment they live in. Also when in drive theres a semi loud ticking heard from inside cabin thats from coming from motor that gets louder with acceleration. Heres something that might not be related i just bought truck 3 weeks ago.
Depending on the vehicle, this voltage threshold may be different, so check your repair manual to be sure. Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. After careful interrogation of the young driver he told the true story. You should have less than 1 Ω resistance end to end and more than 10 kΩ between them and to ground. It would be very rare to have a shorted sensor, and really rare to have a new one also shorted and setting the same code, but if the wires will reach, you can switch the plugs between the left and right sensors, then erase the code and see if the same one comes back.
Heated 3 and 4-wire O2 sensors on mid-1980s through mid-1990s applications can be changed every 60,000 miles. What are the common causes of code P0132? Lack of engine lubrication can shave years and thousands of miles from the life of an engine. This produces a corresponding change in the O2 sensor reading. This could cause fouling of the O2 sensor. Could any of these be related. To learn how to replace an oxygen sensor, click © 2012 Rick Muscoplat Save.
We posted a picture at the top of this article representing one that fits the Nissan product line. This exhaust gas sensor never stops moving. 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. When the air-fuel ratio becomes lean, the oxygen concentration in the exhaust gas is rich. Using Simple Tools to Diagnose O2 Sensors I accomplished the same goals and retrieve the needed information with my extremely simple generic brand automotive scan tool. Inside the bulb are two strips of platinum that serve as electrodes or contacts. You'll have to chisel it out of the protective glop to replace it, or you can bypass it with a jumper wire.
The idea of using Wizards for some of the most common tasks that people would use it for was a stroke of genius. It is capable of changing between 0. Also visit the main check engine light page for more. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. Common Symptoms Check Engine light is the most obvious symptom for Error Code P0158, as it will not usually cause drivability issues, since it only suggests an input that measures the efficiency of the catalyst unlike the front Oxygen sensors.
This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Electrical Connection Problems Check for damage to exhaust pipes and catalytic converter. A quick sidebar about this v6 powered Altima in the story. Then go to Step 12. Switch the two rear speakers side-to-side.
My main concern is the transmission not working in overdrive. Older single wire O2 sensors do not have heaters. Heated O2 sensors are used mostly in newer vehicles and typically have 3 or 4 wires. P0138 - Oxygen Sensor Circuit High Voltage Bank 1 Sensor 2 Fault codes never say to replace parts. Possible high fuel pressure can over rich the system.
