Check P2309 Engine Code
When you check engine light came on code P2309 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P2309 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.
Theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
P2309 Possible Solution:
Excessive air inflow can be caused by a vacuum leak, a dirty sensor or, an exhaust gas recirculation valve not closing properly. If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance.
P2309 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Fuel And Air Metering (Injector Circuit Malfunctions Only)||Throttle/Pedal Position Sensor/Switch A Circuit Intermittent||Cold Start Injector 1 Malfunction||Reverse Input Circuit|
The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
P2309 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP2309 OBD-II Trouble Code The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Each cylinder is equipped with 1 dual-output coil. Meaning one coil mounts directly over one of the dual spark P2309 code.
Reason For P2309 CodeThe reason of P2309 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.
P2309 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.
