Check P009D Engine Code
When you check engine light came on code P009D the reason should be . However your vehicle's manufacturer may have a different definition for the P009D 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.
P009D Possible Solution:
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
P009D Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||Ambient Air Temperature Sensor Circuit Low||Crankshaft Position Sensor A Circuit Malfunction|
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.
P009D OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP009D engine trouble code is about .
Reason For P009D CodeThe reason of P009D OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.
P009D DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
