Steps 8 - 9
Test Description
Number(s) below refer to the step number(s) on the Diagnostic Table.
IMPORTANT: Be sure to use the same diagnostic test equipment for all measurements.
4. Applying 34 kPa (10 in of Hg) vacuum to the MAP sensor should cause the voltage to be 1.5 to 2.1 volts less than the voltage at Step 3. Upon
applying vacuum to the sensor, the change in voltage should be instantaneous. A slow voltage change indicates a malfunctioning sensor.
6. Check vacuum hose to sensor for leaking or restriction. Be sure that no other vacuum devices are connected to the MAP hose.
7. IMPORTANT: Make sure electrical connector remains securely fastened.
Move sensor electrical connector by hand (only) while watching scan tool to check for intermittent connection. Output changes greater than 0.10
volt indicate a bad connection. If OK, replace sensor.
