U253D Trouble Code

Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

A common cause of code U253D is the failure of Air Suspension Warning Lamp Circuit Open, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
Variable Camshaft Timing solenoid stuck open
