This document must not be used in any way, such as copying and redistributing to third parties, without our consent P0069–00: Manifold Absolute Pressure - Barometric Pressure Correlation Overview: Code Cause Effect on Vehicle Fault Code: P0069- 00 Manifold pressure sensor drift is above limit 1.MIL Lamp On Component Details: The sensor serves to measure the absolute intake-manifold pressure as well as the temperature of the intake air stream of internal-combustion engines. The piezo-resistive pressure sensor element and a suitable circuitry for signal amplification and temperature compensation are integrated on a silicon chip. The measured pressure operates from above to the active side of the silicon diaphragm. The temperature sensor element is an NTC-resistor. The sensor is installed after turbocharger at inlet manifold of the engine. Checkpoints: 1. Check wiring harness of Boost temperature (T-Map) sensor circuit 2. Check boost pressure & temperature sensor for any damage Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check connector is connected properly Physical check Step 2 Check for continuity between sensor connector and ECU Harness Check the End to end continuity using multi-meter Step 3 Check the sensor physically Physical check Step 4 If the problem persists, replace the sensor - Circuit Schematic Diagram: Component Location and Image:
