1 or 2 MAP sensors in 2010 RR 5.0 HSE (P0106)

1 or 2 MAP sensors in 2010 RR 5.0 HSE (P0106)​

Local O'Riely auto parts told me there are two MAPs in my 2010 RR 5.0 HSE:
1-Standard Intermotor Manifold Absolute Pressure Sensor On Manifold (O'Reily P/N AS419)
2- Standard Intermotor Multi-Purpose Sensor on Throttle Body (O'Reily P/N AS420.)
Is their info correct? Do I have to replace both sensors for P0106? All help would be much appreciated.

I've only got 1 on my 2010 rr hse. on the top of the intake just behind where the air intake attaches to the intake manifold.

Regards,
Jon

They probably mean MAF sensors, one on each air intake box tube

O'Reilly's info is a bit muddled. You've got one MAP sensor behind the throttle body—that's the one throwing P0106. There might be other pressure sensors in the intake system, but you don't need to replace two different sensors for this code. Before buying anything, pull the sensor's live voltage data with a code reader and check for vacuum leaks around the intake. Vacuum leaks are notorious for causing this exact code on the 5.0L and they're way cheaper to fix. If the sensor voltage is actually erratic or stuck, then replace just the primary MAP sensor.
