troubleshooting a OBD-II P1660 for 98 Acura 2.5 TL
have found a trouble code P1660 on my 1998 acura 2.5 tl. my vehicle now will not start. when i step on the breaks my car will not allow me to take my gear out of parking and into other gears i try resetting the code, but everytime i stick in my keys into the ignition and try to start the car, the trouble code starts again. i want to know what i need to purchase and what steps i need to do to diagnose and fix this problem.
If the Check Engine Light comes on right away, be sure to perform the K-Test. Your ECM may be bad.
P1660 = A/T FI Signal A Circuit Failure. This code being thrown may be a symptom and not the cause of your problem. The real problem could be a failed ECM or main relay. The focus needs to on getting the CEL to come on for 2 seconds and then go out. Normally, this situation arises from a bad fuse, ECM, main relay, or ignition switch.

i found out that it was a fuse under the steering colomn that was burnt ( 20Amp for ecu, sat ecu or something like that). WHen fuse is replace, my car starts, gets into gear and it runs. HOwever another roblem i am encontering now is that once i replace that fuse, it blows again within 2 minutes of driving and all codes return ( P1660, P0135, P0141).
The codes being thrown may be accurate--I'm just not sure. If you believe they are accurate, then check out Oxygen Sensors 1 and 2. Ensure the main ECM ground, located on the thermostat housing, is clean. Perform the K-Test on the ECM--let's see what reading you get.
If you could substitute a known-good ECM, and see if the problems go away, that would be ideal. Does the fuse blow after 2 minutes, if you turn the ignition key to ON (Position II)?
