If both the idler air sensor and the oxygen sensor shows malfunctioning which should be replaced first on a ford contour 95?
First, change the oxygen sensor and the air filter. Clear the codes and see if the idler air sensor code comes back.
Why would a 1999 Chevy Tahoe continue to put out crank sensor and map sensor codes after both have been replaced?
You need to clear the codes with a engine scanner.
How do you know which oxygen sensor to replace?
To determine which oxygen sensor to replace, start by checking for diagnostic trouble codes (DTCs) using an OBD-II scanner, as these codes can indicate which sensor is malfunctioning. Common codes for oxygen sensors include P0131 to P0135 for upstream sensors and P0136 to P0141 for downstream sensors. Additionally, inspect the sensor visually for any physical damage or corrosion, and consider the sensor's age and mileage; if it's been in use for over 100,000 miles, it may be due for replacement regardless of codes.
Where do you find the oxygen sensors in the 2001 six cylinder Toyota Solara and how do you know which one is needing to be replaced?
In the 2001 six-cylinder Toyota Solara, the oxygen sensors are located in the exhaust system: one before the catalytic converter (upstream) and one after it (downstream). To determine which sensor may need replacement, you can check for diagnostic trouble codes (DTCs) using an OBD-II scanner; codes related to oxygen sensor performance issues will indicate a faulty sensor. Additionally, physical inspection for signs of damage or contamination can help identify a failing sensor. If the vehicle exhibits poor fuel economy or rough idling, these may also suggest a malfunctioning oxygen sensor.
What if 2003 Yukon keeps getting PO171 and PO174 codes Unlikely both or all 4 oxy sensors are bad?
Have you had your 4 oxygen sensors replaced? It turns out when they replaced my oxygen sensors, they were after market parts so the service engine light did not come and gave codes even though they were replaced.
How do you know if the oxygen sensor is bad?
Generally, the onboard diagnostics will tell you when you scan the computer codes.
What do these trouble codes mean on a 94 Lincoln town car 111 172 176 181 and 189?
I just ran a diagnostic test on my 1993 Towncar yesterday and got the codes 172 (oxygen sensor), 175 (oxygen sensor, 176 (oxygen sensor), 181 (rich), 189 (rich) and 332 ( gas resonator flow detected if that help you any.
What could be the problem if you get codes that say intermitted signal lost at camshaft sensor when you replaced the distribtor with a new camshaft?
Camshaft sensor interrupter will send that code.
How do you repair codes P1137 and P0141 on a 2000 Chevy Cavalier?
Both codes indicate a problem with the oxygen sensor on Bank 1 Sensor 2. Bank 1 is the side off the engine with the number one cylinder. If there are more than one oxygen sensors on that side then Sensor 2 would be the second one.
What does trouble code 44 mean for a cutlass supreme 1989?
Code 44 is an Oxygen sensor code meaning exhaust is to lean. Replace Oxygen sensor. Then clear codes. This should solve the problem.
I have replaced plugs plug wires fuel filter fuel pump oxygen sensor coolant temperature sensor.my 1993 ford ranger 2.3 misses at steady speeds why?
check your egr that is not plugged also do you have any engine codes?
What causes a speedometer not to work in a Cherokee sport. I replaced the speed sensor and speedometer.?
Is the TCM working normally and throwing no codes?
