Nissan Factory Service Advisories & Field Notes
Cleaning a Nissan throttle body will cause a high idle (1100-1300 RPM) and code P0507. You MUST perform the manual 3-step 'Throttle Valve Closed', 'Accelerator Released', and timed 'Idle Air Volume Learning' sequence to reset base idle.
Nissan QR25 and VQ35 engines use metal-tipped sensors prone to internal solder cracks. When replacing, ALWAYS replace both the camshaft sensor and crankshaft sensor simultaneously with updated metal-shielded Hitachi OEM sensors.
