I would try oxygen sensor but you need to put it on the machine which will tell you for sure. good luck
The only fix is to replace it. If you are mechanicly inclined, this is a doable deal. Before you replace the sensor you should check the wiring for resistance you can use a volt/ohms meter (vom) and test the continuity of the wiring to the sensor.
You can test the engine coolant sensor by using an ohmmeter. Attach the positive and negative probes to the terminals of the coolant sensor.
Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
only in California
You need to pull the code. Don't take a chance.
o2 sensor My list shows P1167 Invalid Test,throttle not depressed
oxygen sensor is basically a thermocouple. its voltage will vary with the oxygen content in the exhaust stream and must be heated to its operating temperature in order for it to work. most new sensors are of the heated variety so they will work sooner and at idle when the older versions won't. if your sensor is lazy, nothing you can do for it but replace it. sensors can be destroyed by leaded fuels, silica contamination and such or someone trying to test one without proper test equipment.
No. Check the battery first. Then test for spark, fuel pressure, and test your coils.
Yes, along with dozens of other things.
Many auto parts retailers can test it for you if you remove it and take it in.
