Check Engine Light on a 95 Honda Accord
1. I've got an illuminated check engine light.
2. What i notice while driving is: the rpm gauge works sporadically or not at all. The vehicle jerks a little during speed changes. 2. After hooking a OBD II scanner to it...I got po725. 3. The service manual says po725 ='s Symptom: lock-up clutch does not engage. Possible Causes: Disconnected ignition coil connector Short or open in ignition coil wire Faulty ignition coil 4. Service Manual goes on to say in the Troubleshooting Flowchart: Disconnect harness from the Transmission Control Module TCM and measure for battery voltage with the ignition switch on; at leads a5 and a 26. -is there battery voltage? -NO repair open or short in the wire between the A5 terminal and the ignition coil. -YES Check for loose TCM connector. If necessary substitute a known good TCM and recheck. 5. After i measured the voltage, with the ignition switch on... i got a reading of 3 volts. Well below the 12 volt reading i get at the battery. The service manual gives a yes or no answer...I'm sort of in-between with 3 volts. 6. Do i have a bad ignition coil? |
