I am personally going back to answer your unanswered questions. Other malfunctioning systems affect its operation. Lean oxygen sensor values will result in an increase in pulse-width, excessive emissions, surging, hesitation, and potentially catalyst damage. This provides adequate oxygen for storage while maintaining cool enough operating temperatures to prevent catalyst damage. I have only been a free contributor to this site for the last 4-months.
Hope this helps, Good luck. Typical values from the downstream oxygen sensor s are between 550- 900mV at idle. It covers the vehicle inside and out from interior to exterior. When the exhaust sample is rich, there is less oxygen content in the exhaust as compared to the atmosphere. The oxygen sensor will sense only the increased oxygen content and input to the computer will be below bias voltage levels.
I do not know if you still need this information, however I am answering it either way. This manual is just like a paper manual but allows you to print the exact pages you need and simply throw them away when youre done. With relatively richer mixtures present around the downstream oxygen sensor, voltage inputs to the computer will be above the 450mV bias voltage. If the catalyst is operating effectively, the downstream oxygen sensor will cycle when the catalyst is flooded with oxygen. While the downstream oxygen sensor is used to monitor catalyst efficiency, the upstream sensor has a pronounced effect on performance. Do you have a code that describes which O2 sensor is not responding correctly? Hope this helps, Good luck. In addition to controlling the converters operating conditions for emissions control, the computer uses the oxygen sensors to tailor fuel trim providing a balance between fuel economy and performance.
Be prepared for it when it happens by simply purchasing this service manual for later use! Improper rich indications will cause lean operating conditions that may result in loss of power, hesitation, surging, poor idle quality and possibly converter damage. You just buy the parts, no more high labor rates. The simple fluid changes that you pay hundreds for are covered as well as any repair you can think of. The manual includes pictures and easy to follow directions on what tools are needed and how the repair is performed. No one else will offer you this but I am 100 sure that you will be completely satisfied with this manual! It covers the vehicle inside and out from interior to exterior. I would say step one is replacing the sensor, reset the code and take it from there. Malfunctioning heaters also allow the sensors to cool down during periods of extended idle.
I would say step one is replacing the sensor, reset the code and take it from there. Many people are scared to touch their cars because it seems difficult. You will now be able to do the repairs and services that you pay hundreds for yourself. Sensor values that indicate lean conditions will cause the computer to command changes in short term fuel strategies. This is only true when you do not have the resources and tools available for when that time comes! The manual includes pictures and easy to follow directions on what tools are needed and how the repair is performed.
This is only true when you do not have the resources and tools available for when that time comes! The oxygen sensor provides the computer with necessary information to maintain favorable operating conditions for the catalytic converter. Abnormal sensor activity has a profound effect on pulse-width and fuel trim strategies. When the catalyst performs properly, available oxygen is used resulting in low levels oxygen in the exhaust sample. The greater the difference between ambient oxygen and exhaust oxygen content, the greater the voltage produced. For smoother drives and trouble-free vehicle fixes, change parts the instant they show signs of failure. Learn how to find whats wrong, what you need to fix it and how with this manual.
If the timing belt has not been changed recently, when was it last done? It has several Diagrams you will need for your Timing Belt replacement. Posted on Feb 22, 2011 It sounds to me like a timing issue. When the output voltage from the sensor drops below bias voltage levels, the computer will command a rich mixture again. It is the same as a paper manual but for a fraction of the cost. It will cover everything from oil changes to rebuilding the transmission. Click on the following direct Link.
If the timing belt has not been changed recently, when was it last done? Virtually all defective or worn out components, if unmonitored, can contribute to additional problems to connected or nearby parts. It is the same as a paper manual but for a fraction of the cost. Additional fuel can cause the catalyst temperatures to rise due to an afterburner effect in the converter. Included are the Cover Bolt Locations, Tool Needed and Marks for your specific engine. My guess is that the sensor will need to be replced, then if it is only a code issue, the problem should resolve itself. .
Learn how to find whats wrong, what you need to fix it and how with this manual. It will cover everything from oil changes to rebuilding the transmission. Did you recently have the timing belt changed on the car? Many people buy this manual just to have it around for when the inevitable happens. Sooner or later, maintenance will need to be performed. Sooner or later, maintenance will need to be performed. See below for a list of items that most of our manuals cover.
