P2262 Powertrain The engine computer commanded boost but saw almost none, pointing to a mechanical turbo… Moderate P2263 Powertrain Boost isn't tracking its target closely enough: too low, too high or too slow to respond. Moderate P0508 Powertrain The idle air control circuit reads low voltage – a shorted valve coil, lost power feed or wire… Low P0511 Powertrain The computer can't drive the idle air control valve properly – typically an open winding… Low P0561 Powertrain System voltage jumps up and down instead of holding steady – often loose terminals… Low P0563 Powertrain The engine computer sees too much supply voltage – usually an overcharging alternator cooking… Moderate P0571 Powertrain The engine computer doesn't trust the brake pedal switch signal – cruise control usually stops… Low P0572 Powertrain The PCM never sees the brake pedal pressed – brake lights may be out and the car may not shift… Moderate P0573 Powertrain The PCM thinks the brake pedal is always pressed – brake lights stay on, often from a missing… Moderate P0610 Powertrain The engine computer's vehicle configuration is missing or doesn't match the car – usually after… Low P061B Powertrain The ECM's safety monitor disagreed with its own engine torque calculation – often bad input… Moderate P0620 Powertrain The engine computer found a fault in the wire or signal it uses to command alternator output. Moderate P0621 Powertrain A fault in the alternator's 'L' circuit – the line behind the charge light or the ECM's turn-on… Moderate P0622 Powertrain The alternator's field control or field feedback circuit is faulty – output may drop out… Moderate P0627 Powertrain The PCM's fuel pump command line has no complete circuit – a dead relay coil, open wire, fuse… Moderate P0628 Powertrain The fuel pump control wire is pulled toward ground – a chafed wire, shorted relay coil or wet… Moderate P0629 Powertrain Battery voltage is leaking into the fuel pump control line – a short, corrosion bridge… Moderate P0630 Powertrain The engine computer has no VIN stored, or one that doesn't match the car – a classic after… Low P0641 Powertrain The PCM's shared 5-volt supply 'A' is missing or out of range – often one shorted sensor… High P0651 Powertrain The PCM's second 5-volt sensor supply is out of range – usually a pedal, throttle or pressure… Moderate P0685 Powertrain The engine computer can't switch its own main power relay – open coil, blown fuse or broken… High P0686 Powertrain The main relay control line is being pulled to ground – usually a shorted relay coil… Moderate P0687 Powertrain The main relay control line sits at battery voltage – the relay may never switch on or never… Moderate P0690 Powertrain The ECM still sees power coming through its main relay when the relay should be off – often… Low
