P0709 Engine Code Repair
Meaning of P0709 engine trouble code is a kind of powertrain trouble code and P0709 code can be about replacing a broken oxygen sensor can eventually lead to a busted catalytic convertor which can cost upwards of $2,200. Taking your car into a shop will cost you around $210 depending on the car. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Regardless of how you approach it, you should get this fixed right away.
P0709 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P0709 code is occuring now you should check P0709 repair processes.
Now don't ask yourself; What should you do with P0709 code ?
The solution is here :
P0709 Possible Solution:
Air Conditioning Pressure Sensor (ACP) Insufficient Pressure Change Each time the A/C clutch engages, the PCM is looking for a pressure change in the refrigerant. If the change in pressure is outside of the calibration the DTC will set. A/C system mechanical failure Open ACP or VREF circuit A/C sensor damaged A/C system electrical failure A/C clutch always engaged Verify A/C system function, including refrigerant charge.
P0709 Code Meaning :

0
Crankshaft Position Sensor A Circuit Malfunction
9
Clutch Position Sensor Circuit Malfunction
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
P0709 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0709 OBD-II Trouble Code The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and P0709 code.Main reason For P0709 CodeThe reason of P0709 OBD-II Engine Trouble Code is Fuel Temperature Sensor B Circuit Range/Performance. |
P0709 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
