51 - EGR System & REGT Sensor Circuit Got this from the Check Engine Light Guide. What does this mean? How do I diagnose/fix this? |

Most of the time it is a blocked passage or plugged up egr valve. Here is a link to the 94 FSM. Look in section 6E2-A1 ENGINE COMPONENTS WIRING DIAGRAMS DIAGNOSTIC CHARTS. Starts on page 54. http://geometroforum.com/topic/5044844/1/#new |

Thanks, I read through page 54-55. The diagnosis flowchart seems helpful but I have some questions. How do I access the ECM? What is a test light? |
