On newer models and replacement parts, the inlet manifold pressure sensor has been improved. Older sensors would drift out of calibration, feeding the ECU incorrect data and triggering DF1551 erroneously. Updated sensor revisions provide more accurate data, reducing false positives. : The most frequent dashboard message

Always use an OEM (Original Equipment Manufacturer) sensor. Cheap aftermarket sensors often have the wrong voltage calibration, causing the DF1551 code to return within a week. Diagnostic Tips for Professionals Older sensors would drift out of calibration, feeding
