Where are errors stored on the EEC-IV?
Where are errors stored on the EEC-IV?
Additionally the EEC-IV runs a continuous self-test during normal operation, and errors detected will be stored in the EEC’s Keep Alive Memory, or KAM. These codes can then be extracted from the KAM for diagnosis later.
What are the problems with the Ford EEC-IV?
Distributorless Ignition System Coil Pack 3 Circuit Failure (3.0L SHO 3.8L SC) Distributorless Ignition System Coil Pack 1 Circuit Failure (3.0L SHO 3.8L SC) Loss Of Ignition Diagnostic Monitor LH Side (2.3L) Distributorless Ignition System Coil Pack 2 Circuit Failure (3.0L SHO 3.8L SC) Spark Output (SPOUT) Signal Default To 10°.
Where is the EGR valve on a Ford EEC-IV?
EGR Valve Position/EGR Pressure Feedback EGR Circuit Above Maximum Voltage (Others) DC Motor Idle Speed Control/Idle Tracking Throttle Position Sensor Open Circuit (2.3L CFI & 2.5L HSC) Distributorless Ignition System Coil Pack 3 Circuit Failure (3.0L SHO 3.8L SC)
What can the EEC-IV do for your car?
One of the many other capabilities of the EEC-IV is its ability to diagnose a poorly running engine. Through the use of self-contained sensor tests the EEC-IV can provide information about failed sensors, or sensors picking up abnormal operating conditions which can cause your car to perform poorly.
Where does the voltage from the EEC relay come from?
This voltage comes directly from the battery positive terminal across a fusible link on the starter motor solenoid (on the fender). Ground is always present on circuit 1. As soon as the ignition switch powers up circuit number 2, the EEC Power Relay closes circuit 3 to circuit 4 .
What is the error code for engine speed input circuit intermittent?
Error Code P0728 is defined as Engine Speed Input Circuit Intermittent. This is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made since 1996 up to present.
How to troubleshoot Ford EEC IV engine control?
Place the gear shift lever in Neutral (manual transmission) or Park (automatic transmission). CAUTION – Failure to perform this step may result in the vehicle moving when the starter is subsequently engaged during the test. 2 – Disconnect the S terminal wire at the starter relay.
What is the low current circuit on a Ford EEC?
Every Ford EEC Power Relay has two basic circuits and for the purpose of our discussion, we’ll call them: A low current circuit. This circuit can be identified by the wires labeled with the numbers 1 and 2. The low current circuit is the control circuit that ‘closes’ or ‘opens’ the high current circuit.
