2009 Mazda CX-9 P0118 and P0122 OBD2 Error: Camshaft/Crankshaft Sensor Issues or Timing Chain Fault?

Model: 2009 mazda cx9 Fault Code: P0118 Posted: 2015-09-08 12:02

I'm experiencing OBD2 fault codes P0118 and P0125 on my 2009 Mazda CX-9. My mechanic suggested a faulty timing chain, citing issues with the camshaft and crankshaft position sensors. However, I'm unsure if this diagnosis is accurate given these specific error codes. Can anyone confirm whether P0118 (Intake Air Temperature Sensor Range/Performance) or P0122 (Throttle Position Sensor Range/Performance) are typically linked to timing chain problems? What are the actual causes of these codes in a 2009 Mazda CX-9?

The reference to 'camshaft and crankshaft sensor' is likely misleading. P0118 and P0122 are related to intake air temperature and throttle position sensors, not directly to timing chain issues. For accurate diagnosis, consult official OBD2 code explanations: https://www.obd-codes.com/p0118 and https://www.obd-codes.com/p0122.

Two mechanics have suggested a timing chain issue, but this may not be directly related to P0118 or P0122. Timing chain problems usually trigger different codes like P0340 or P0341.

It's possible that the symptoms are being misattributed—P0118 and P0122 relate to sensor readings, not mechanical timing components. A proper diagnostic scan is needed to confirm root cause.

I recommend visiting auto parts stores like AutoZone, Advance Auto Parts, or O'Reilly's for a free OBD2 scan. This will provide accurate codes and help identify whether the issue lies with sensors or mechanical components.
