1999 Mercury Cougar 6 cyl Front Wheel Drive Manual 122k miles
I bought a 99 Mercury Cougar 2.5 MTX. The speedometer didn't work when I bought it. I changed out the vss tried two new ones and it still doesn't work. I have a different cluster same thing and I have also tested out the the harness with the test points the the ford shop manual for the 99 cougar says to test. I'm not sure what else to check for. I verified that the vss plug was getting power and ground; the shop manual also had another test for resistance. Here are the test the I ran. Test 1: I had to measure the resistance between HEC C808b pin 9, harness side and VSS pin 2. It states that if the resistance is less then 5 ohms to go to the next test. My resistance was less than 5 Test 2: VSS ground, test vss pin 3 and ground. If the resistance is less than 5 ohms to continue to the next test. My resistance was less than 5 Test 3: Voltage, test vss pin 1 and ground if voltage is greater than 10 volts replace the vss. My voltage was at 12. How do I check the signal when I have the car running in the air?
have the same problem?
