Vehicle will run fine for awhile stop/start then check engine light will come on then stop and let sit and wont start. several dtc codes appear indicating sensor heater ckt bank 1, sensor 1 and 2/egr flow circuit.... I believe the ecu is malfunctioning... how can I test the ecu ????
Substitute it with a known good one is the quickest method

sounds like the timing belt it has a interference engine so if the timing belt broke you could have bent rods and cracked pistons or worse. good luck

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.
Testimonial: "Thank you for the help. We will continue to check all fuses and wires."
