Couple of engine codes for your reading pleasure...
Hi all, my '94 4x4 has been acting funny and lighting up the CEL so I took it to Advance Auto Parts and got the codes read.
Here's what I got: KOEO Code 335 EGR PFE/DPFE Volts Out Of Range KOEO Code 539 A/C Or Defrost On <--- I know I can easily fix this one by turning During Self-Test them off. Memory Code 172 HO2S (sensor) System Lean (Bank 1) Memory Code 176 HO2S (sensor) System Lean (Bank 2) Memory Code 181 No Definition Available Memory Code 186 No Definition Available Memory Code 189 No Definition Available Memory Code 211 Profile Ignition Sensor Circuit Malfunction Memory Code 556 Fuel Pump Primary Circuit Circuit Malfunction Now, talking to the guy at AAP he said to start with the egr valve since that might trigger all the other items on the list. What do you guys think? Is there a site that has pics and details about where the egr valve is and how to check it and clean it? Thanks in advance for any help you can give. Brett |
