No. You have other problems involving the induction, fuel pressure, or spark on the engine. If the check engine light hasn't come on, then a good place to start is with is the fuel and air filters. If they are good, then next would be plugs and wires. Also look for vacuum leaks. We had an 87 that ran terribly, replaced all the above, and found out that the MAP sensor was bad. No codes coming from the PCM. Frustrating, and time consuming.
Oxygen Sensor Circuit (Rich Exhaust). This may of may not be a defective O2 sensor. It may be something else that is effecting the O2 sensor. But considering the vehicle is 22 years old, I would suspect the O2 sensor needs replacing. I would replace the O2 sensor.
It would depend on the vehicle. most likely the vehicle would run, but not well. this puts the computer in limp home mode. most car computers will allow the vehicle to run with one major sensor undone.
The bank 1 sensor 2 O2 sensor on that vehicle should be the sensor after the catalytic converter. Inspect the wiring for damage, cuts and such, if the wiring looks okay it is probably the heater circuit within the sensor, replace the sensor. Unplug the wire harness from the sensor and cut the wires off at the sensor. This will allow you to slip a 7/8" box wrench over the sensor to remove it. Install the new sensor using a 7/8" open end wrench, tighten it as you would a spark plug. Reconnect the wire harness.
A TPS is normally known as a "throttle positioning sensor" price would be dependant on the vehicle.
I would test the temperature sensor first. Then have the car scanned.
To help you turn your backup sensor on I would need more information. What does the backup sensor go on? What type of vehicle? What year is it? an what model vehicle is it?
PLease have the codes read with a scanner and that will point you in the correct direction. If i was to hazard a guess i would say the Vehicle Speed Sensor or circuit has gone bad.
Knowing the year, make and model vehicle you have would help but, if it has a crankshaft sensor maybe the sensor or the sensor wiring got damaged.
The engine would be running poorly and the check engine light should be illuminated with related codes.
A Vehicle Speed Sensor (VSS) senses the speed of the vehicle. Used for automatic transmission shift points and other electronics. Another speed sensor would be a wheel speed sensor. This one monitors wheel speed for ABS and Traction control.
what kind of sensor? tells a chip/circuit the value of something, and then w.e chip/circuit would respond accordingly by doing actions
It would depend on what year the vehicle is.
P0141 is heated oxygen sensor circuit malfunction you need to check the supply voltages to the sensor.
More than likely the heater burned out in the B1 S1 O2 sensor. First locate the B1 S1 O2 sensor, it would be the one threaded into the exhaust pipe directly behind the bank of cylinders that contain the number one cylinder. Inspect the wiring leading to it looking for damage/cuts in the wiring. If the wiring looks good, disconnect the sensor from the vehicle harness, cut the wires off of the bad sensor, slip a 7/8" box wrench over the sensor and remove it by turning counterclockwise. Install the new sensor using an 7/8" open end wrench and tighten as you would a spark plug. Plug the new sensor into the vehicle harness and your done.
Bank 1 would be the bank of cylinders that contains the number 1 cylinder.Sensor 1 would be the sensor placed before the catalytic converter (AKA the upstream sensor).
You cannot disable a vehicle speed sensor on any EFI vehicle without causing a host of problems. I'm not sure why anybody would want to.
Depends on What kind of Vehicle Your Asking About ,And What year If Its A Newer vehicle I Would Say that The VSS Has Went Bad. VSS Means Vehicle ,Speed ,Sensor......
HO2S (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1)symptomsOther than the MIL light illuminating you may not notice any performance issues.causeA short in the O2 sensor heater circuit or the sensor itselfA faulty O2 sensor heaterWiring or connectors are broken or frayed to the sensor or relayBad PCM or ECMThe fixCorrect wiring short or loose connector found in inspection.and/orReplace the bank 2 sensor 1, O2 sensorReplace PCM if circuit has failed and no wiring issues present, good O2 sensor
P0050: HO2S Heater Control Circuit. H: Heated Oxygen Sensor Bank 2 Bank 1 is the side that cylinder 1 is located on. Bank 2 would be the opposite side. Sensor 1 would be the first sensor in the exhaust line starting at the engine. Most likely the sensor in front of the catalytic convertor. Check the wiring and connector to the oxygen sensor. If wiring is ok, just replace the sensor. Might switch the two sensor to see if the problem follows the sensor. If problem stays on bank 1, then check the circuit wiring.
Open Circuit. Replace the sensor unit.
Vehicle speed is typically monitored at the transmission output shaft, therefore, the sensor would be located on the transmission tail houseing.
It would help if you stated what type of vehicle it is. There are several 2.7 engines in different vehicle types.
If you are replacing an O2 sensor with a new one, unplug the sensor from the vehicle wire harness, cut the wires off at the sensor, slip a 7/8" box wrench over the sensor and remove the sensor counterclockwise, install new sensor using a 7/8" open end wrench, tighten it as you would a spark plug, reconnect the sensor back into the vehicle harness, done.
