causes very poor gas mileage
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
motorcraft . com just shows ( 1 ) oxygen sensor for all available engines in a 1991 Ford Ranger
It just has ( 1 ) oxygen sensor , before the catalytic converter ( upstream )
the o2 sensor is located on the exaust manifold
The O2 sensor after the catalytic converter.
you can breath
An oxygen sensor is bad when it is no longer performing inside a set of parameters that are designated and optimal. The oxygen operates in a very narrow window of voltage and provides feedback to the engine to adjust the air/fuel ratio to maintain performance and emissions. If the sensor is bad and returning poor data, the performance, emissions and mileage will suffer.
There are 2 heated exhaust gas oxygen sensors , 1 screwed into the outlet on each exhaust manifold on a 1993 Ford Ranger 4.0 L .
Go by the miles travelled. Refer to the owners manual for the replacment schedule. A new oxygen sensor will give you better fuel economy and performance.
Upstream Oxygen Sensor heater performance. That will be the first oxygen sensor in the exhaust pipe ( closest to the engine ) on the passenger side head. You need to check the wireing connector that hooks to the oxygen sensor for a broken wire are bad connection. If you find no problems, then replace oxygen sensor.
there are 2 and they are both under the vehichle on the exaust manifold
There is one in the exhaust system before the catalytic converter and sometimes one after it.
On a Ford Ranger ( V6 engine ) Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
The oxygen sensor on a 98 Chevy K1500 truck is located in the exhaust manifolds. It monitors oxygen levels in the exhaust gases and allows the computer to make adjustments for optimal performance.
in the exhaust pipes behind & in front of converters
A bad O2 sensor can affect gas mileage. It is an emissions sensor, so when it goes bad, it does not reflect emissions performance on the car, which could cost a lot in gasoline.
P0451 - Evap Emission Control System Pressure Sensor Performance Improving my answer - P0451 - intermittant open or short in the fuel tank pressure sensor ( FTP ) or the FTP sensor signal
Just in front of the Cat converter, drivers side.
Bank 1 is the passenger side of your V6 in a Ford Ranger Sensor 1 is somewhere close to the engine before the exhaust enters the catalytic converter
On the 3.0 L and 4.0 L there are 2 oxygen sensors at the front and 1 oxygen sensor (which monitors your catalytic convertor efficiency) at the back after the exhaust gasses have passed through the convertor. On the four cylinder engine - 1 oxygen sensor at the front - 1 oxygen sensor at the back (downstream of catalytic convertor - monitors catalytic convertor efficiency) Helpfull
Upstream Oxygen Sensor Circuit Slow Response (Bank 1)
It takes a socket tool to remove the sensor. auto zone will sell you the tool to replace it with and refund your money for the tool when you return it
