Particular Troubleshooting Information for 1993 Ford Rangers
### 7. Oxygen Sensor
The oxygen sensor is accountable for measuring the quantity of oxygen within the exhaust and sending this data to the PCM. The PCM makes use of this data to regulate the air-fuel combination. A defective oxygen sensor could cause plenty of issues, together with:
• Poor gasoline financial system
• Tough idle
• Stalling
• Elevated emissions
To check the oxygen sensor, you will want a multimeter. Set the multimeter to the DC voltage setting and join the constructive result in the sign wire of the oxygen sensor. Join the damaging result in the bottom terminal of the battery. The voltage studying ought to fluctuate between 0.1 and 0.9 volts. If the voltage studying is outdoors of this vary, the oxygen sensor is defective and needs to be changed.
The oxygen sensor is situated within the exhaust manifold. To interchange the oxygen sensor, you will want a wrench or socket. Disconnect {the electrical} connector from the oxygen sensor after which unscrew the oxygen sensor from the exhaust manifold. Set up the brand new oxygen sensor within the reverse order of removing.
Superior Code Studying Strategies
