Test DF: Step 90

90) Continuous Memory Code 22: Operate MAP/BP Sensor.  Continuous Code 22 indicates the MAP/BP sensor was out of Self-Test range (1.4-1.6 volts) during normal driving conditions. Possible causes for this code are:

• Faulty MAP/BP sensor
• Faulty wiring harness or connectors
• Unusually high or low barometric pressure.

In KOEO Continuous Monitor Mode (Wiggle Test), observe test equipment while performing the following:

• Connect a vacuum pump to the MAP/BP sensor
• Slowly apply 25 in. Hg to sensor
• Slowly bleed off vacuum from sensor
• Lightly tap on sensor (to simulate road shock)
• Wiggle sensor connector

If a fault is indicated disconnect sensor and inspect connectors. Repair as necessary. If connectors are okay, replace MAP/BP sensor. If a fault is not indicated, go to next step.
