The absolute pressure sensor is connected to the MAP \/ BARO switch solenoid valve by a vacuum hose. The sensor detects ambient barometric pressure and intake manifold pressure and sends a voltage signal to the ECM. As pressure increases, voltage rises. The sensor is not used as an input to control the engine management system. It is used only for on-board diagnosis. Therefore you can have fault codes with no drivability complaint.<\/p>\n<p>You can see both the sensor and switching solenoid have been replaced. The fault codes remained.<\/p>\n<p><a href=\"http:\/\/www.flickr.com\/photos\/autotechdiagnostics\/4414468723\/\" title=\"dscn2823 by Automotive Diagnostic Resources, on Flickr\"><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/farm5.static.flickr.com\/4062\/4414468723_540d783d7f.jpg\" width=\"500\" height=\"446\" alt=\"dscn2823\" \/><\/a><\/p>\n<p>I went directly to the sensor to backprobe the connector with the key ON and engine OFF. The first wire I tested was the 5 volt reference. The reading I obtained was 4.35 volts. Too low for a 5 volt reference. I wiggled the harness and the voltage changed accordingly. Next I cut the harness sheathing back to reveal damaged wires. 1 completely broken and the others with broken insulation. The harness to the sensor has a very sharp bend in it. Over time the wires degraded and finally failed. A quick harness repair and the fault codes were gone.<\/p>\n<p><a href=\"http:\/\/www.flickr.com\/photos\/autotechdiagnostics\/4414473643\/\" title=\"dscn2827 by Automotive Diagnostic Resources, on Flickr\"><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/farm3.static.flickr.com\/2794\/4414473643_f327d31ef6.jpg\" width=\"500\" height=\"272\" alt=\"dscn2827\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Both fault codes point to the absolute pressure sensor.
