I lost all power going about 45 mph Last night after I let off the gas to make a slight right curve and when I pressed the gas again.
My gauges reset and there was a message on the cluster screen that said “SHIFT TO NEUTRAL AND PRESS START AGAIN” (it may or may not have said “AGAIN”).
I pulled over and while still in Drive with the brake pressed, I shifted to Neutral, and pushed Start/Stop and the entire vehicle reset. The ignition clicked nonstop for awhile but the engine did not turn over.
While waiting for AAA, I disconnected my Pulsar LT and tried to start it, but got the same nonstop clicking.
I scanned it and got a code reading: “P16A7: Engine Controls Ignition Relay Feedback Circuit 2”.
ANY and ALL feedback is welcomed.
