1. Turn ignition off. Disconnect APPS harness connector. APPS is located on a bracket, just above fuel injection pump. Start engine and allow the engine to idle. Using DVOM, measure voltage at terminal No. 5 (Dark Blue/White wire) on APPS harness connector. If the voltage is greater than 5.5 volts, go to next step. If the voltage is 5.5 volts or less, go to step 3. I get 5.6
2. Turn ignition off. Turn ignition on with engine off. Using DVOM, measure voltage at terminal No. 5 (Dark Blue/White wire) on APPS harness connector. If the voltage is greater than 5 volts, repair short to voltage on Dark Blue/White wire between APPS and ECM when the ignition is on. ECM is located on driver's side of the engine, just in front of fuel transfer pump and contains a 50-pin connector. If the voltage is 5 volts or less, repair short to voltage on Dark Blue/White wire between APPS and ECM when the engine is running. I still get 5.6 and I dont under stand what to do? I don't understand this statement " repair short to voltage on Dark Blue/White wire between APPS and ECM when the ignition is on." Repair short to voltage? I don't get what this means to do please helps
3. Turn ignition off. Using DVOM, measure resistance between ground and terminal No. 4 (Black/Yellow wire) on APPS connector. If resistance is 10 ohms or greater, go to next step. If resistance is less than 10 ohms, replace APPS. See appropriate REMOVAL, OVERHAUL & INSTALLATION article. I get 39 ohms
4. Start engine and allow the engine to idle. Turn ignition off. Turn ignition on with engine off. Using DVOM, measure voltage at terminal No. 2 (Light Green/Dark Blue wire) on APPS harness connector. If the voltage is 5.5 volts or less, go to next step. If the voltage is greater than 5.5 volts, repair short to voltage on Light Green/Dark Blue wire between APPS and ECM. ECM is located on driver's side of the engine, just in front of fuel transfer pump and contains a 50-pin connector. I get 5.2
5. Turn ignition off. Disconnect ECM harness connector. ECM is located on driver's side of the engine, just in front of fuel transfer pump and contains a 50-pin connector. Using DVOM, measure the resistance of Black/Yellow wire between terminal No. 4 on APPS harness connector and terminal No. 32 on ECM connector. If resistance is 10 ohms or greater, repair open in Black/Yellow wire between APPS and ECM. If resistance is less than 10
