test EGR, see if its closed, it should only open at steady/constant speed

crap! my bad, use this while looking at post#2 pics, jaloppy made laptops!
The terminal pins are as follows:
• Voltage Reference (5v from the EEC)
• Signal Return (Sensor Ground)
• EVP Signal (Varying voltage to the EEC)
Testing parameters are as follows:
• Reference Voltage (5v at pins VREF and SIG RTN)
• EVP Sensor Resistance (< 5000 ohms at pins VREF and EVP)
• EVP Sensor Resistance (> 100 ohms at pins SIG RTN and EVP)
