If you have any doubt as to repairs on your vehicle, please contact your technician. Common Symptoms Check Engine light is the most obvious symptom for Error Code P0157. It can cause drivability issues and has the potential of causing the car to stall out. Both traditional and Wideband Sensors have a heating circuit. By opening the tailgate, you will see two star headed screws. Have you changed the oil lately? A lean mixture of oxygen and gas means that there is too much oxygen in the exhaust. What would be causing this? So do your testing before you automatically throw in a new oxygen sensor.
Try showing some respect and send a private message to 'fnky', instead of thread bombing me. Next, use a medium sized screwdriver and apply steady pressure between the body and the light case. Looks like you are good. Since then I cleared the code and notice the long term bank 1 was at +10 and bank 2 was at +14. But there is no guarantee that will fix it. There is a grounding issue somewhere. I check everywhere with brake clean and Propane for vacuum leaks and couldn't find any.
Enter the 5 character trouble codes in the search box and submit the search. Both have heaters In order for the sensing elements to respond to oxygen levels, they must get hot. Alt ground, Battery ground and Trans ground. Engine running lean could also register lean codes such as P0171 and P0174. Proper fuel pressure should be at 40 psi. Dub Possible answer Dont know if the 04 and 05 are much differant, but this page might help out. For optimum catalyst operation, the air fuel mixture air-fuel ratio must be maintained near the ideal stoichiometric ratio.
The voltage ranges from 0. It's a lot more fun over here now. In some cases, the computer may need to be updated from the dealer. This often turns out to be the sensor. The door stoppers have tension loaded ball bearings in a small case that press against the top and bottom of the plastic-looking bar between the body and the edge of the door.
Next, carefully pry the brake light from the body with a small wedge. There should be a perfect balance in the mixture level of oxygen and gas, as neither lean nor rich is good for the catalytic converter as both can cause it to fail prematurely. The o2's only monitor the exhaust. First you take the screw out under the climate controls. It can definitely cause drivability issues, which can be dangerous when driving at highway speed. Then just un hook your antenna and you're wiring harness from the back and repeat process for the new head unit.
Check for harness making contact with exhaust components. An engine that is running lean could set this code, but usually there will be lean codes P0171 Jeep, P0174 Jeep present. Slightly shaky idle, at times and very intermittent occasionally extended long crank time on a hot soak for 5-10min's of sitting once warmed up. Is this hard to replace Dealer wants 160 labor for the job. Hope this info was helpful to all who own Chrysler and jeep autos with digital odometers. Showed up p0157, no biggie. You should see your codes scrolling on your odometer.
But it can also be an expensive diagnostic tool, especially if it turns out to be a wiring issue, instead of a sensor. Since it aids them in selling parts most parts stores will read your codes for free. . Check the wiring on that sensor before proceeding. Is there any particular reason why you came to my thread, just so you could give a shout out to 'fnky'? Then it's just a matter of slowly but with pressure pulling the in my case chrome trim off around the climate control, stereo and empty space where your screw is located. Then the … stereo mounted in presently will have a screw at each of the four corners; remove those while holding the stereo in place.
The Engine Control Module adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. If the sensor reports a voltage below 0. Question is do these things need to be matched as far as brand go are they arguing between each other or has the faulted sensor fouled the good sensor Is this common in this computerized monitoring maintenance system All the wires look fine and 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. Also, if not addressed properly and in a timely manner, it can cause serious damage to catalytic converter, which can be quite expensive to fix. Removed the old installed the new cleared the code and my wife was happy Yay me This would be the happy ending to the story if she hadnt called me 20 minutes and 10 The check engine is on and the code is p0137 which is supposed to be second oxygen sensor on Bank 1.
