Code questions
I have read several of the archived threads and have not found what I am looking for. I have a code 172 which is HEGO sensor circuit indicates system lean (right side). I have a new o2 sensor in it and have driven it around for 500 miles before the light came back on. I had to weld in a sensor bung so it is only reading the driver side exhaust. It seemed to have started when I hit a large water puddle in the road today what could it be? I also have code 334 and 347 DPFE or EVP circuit above the closed limit of 0.67 volts.
DPFE or EVP circuit above the maximum limit of 4.81 volts. What is delta pressure feedback. I have a new egr valve tube and position sensor on it this just started also. If someone could please help fixing these problems I would appreciate it.
