DPFE or EVP Codes
The check engine light has been coming on in my 1992 ford Club Wagon with a 302.
I scanned it and found two codes (334 and 337) in memory.
According to fordfuelinjection.com
code 334 is caused by DPFE or EVP circuit above the closed limit of 0.67 volts.
and code 337 is caused by DPFE or EVP circuit above the maximum limit of 4.81 volts.
Does anyone have an idea what would cause the voltage limits to be exceeded?
What is the difference between the closed limit and the maximum limit?
