Engine stalling: Codes, Causes & Fixes

P0101 Powertrain The MAF sensor's airflow reading doesn't match what the engine computer expects… Low P0171 Powertrain The engine computer is adding the maximum extra fuel it's allowed on bank 1 and still sees… Moderate P0335 Powertrain The engine computer lost the crankshaft position signal. Expect stalling or a crank-no-start. High P0340 Powertrain The computer lost the camshaft signal on bank 1. Expect long cranking, less power… Moderate P0505 Powertrain The engine computer can't hold idle speed where it wants it – usually a dirty or sticking idle… Low P0562 Powertrain The engine computer sees too little supply voltage – usually a charging, battery or ground… Moderate

P0001 Powertrain The PCM can't drive the solenoid that meters fuel into the high-pressure pump. Often a no-start… High P0018 Powertrain The bank 2 intake cam is out of step with the crankshaft on a V or boxer engine; chain wear… High P0087 Powertrain Measured fuel pressure has dropped well below what the engine computer is asking for. High P0093 Powertrain Rail pressure is dropping faster than injection explains: fuel may be escaping. Stop and check… Critical P0200 Powertrain The ECU found a fault in the injector control circuits that it can't pin on one cylinder, often… High P0216 Powertrain The ECU can't control or confirm injection timing, usually on a diesel with an electronic… High P0231 Powertrain Voltage on the wire feeding the fuel pump is too low while the pump is supposed to be running. High P0320 Powertrain The computer lost the engine speed (rpm) signal. The engine can stall suddenly or refuse… High P0335 Powertrain The engine computer lost the crankshaft position signal. Expect stalling or a crank-no-start. High P0337 Powertrain The crank sensor signal line is stuck near 0 volts, usually a wire shorted to ground. Often… High P0338 Powertrain The crank signal line sits at 5 or 12 volts and stops switching: open ground, open wire… High P0339 Powertrain The crank signal drops out for moments at a time. Classic sign: stalls when hot, restarts once… High P0524 Powertrain Measured oil pressure fell below the safe minimum. Stop the engine now and check the oil before… Critical P0641 Powertrain The PCM's shared 5-volt supply 'A' is missing or out of range – often one shorted sensor… High P0642 Powertrain The PCM's 5-volt supply 'A' is being pulled below spec, usually by a short to ground in one… High P0685 Powertrain The engine computer can't switch its own main power relay – open coil, blown fuse or broken… High P0742 Powertrain The converter lockup clutch stays applied when it should be released, which can stall… High P07A3 Ford · Powertrain The PowerShift's odd-gear clutch isn't letting go when the TCM commands it open, so the car… High P1217 Nissan · Powertrain Nissan's ECM saw engine coolant get hotter than it should, usually because the radiator fan… Critical P1295 Hyundai · Powertrain Hyundai's engine computer no longer trusts the electronic throttle and has cut power as… High P1299 Ford · Powertrain The engine got so hot that the Ford PCM is shutting off fuel to cylinders to save it. Stop… Critical P1362 Honda · Powertrain The PCM gets no signal at all from the top dead center (TDC) sensor; stalling or a no-start… High P1682 Chevrolet · Powertrain The engine computer's two ignition power feeds disagree, which can cause stalling or Reduced… High P2105 Powertrain The engine computer shut the engine off on purpose because it could no longer control… Critical P2107 Powertrain The processor supervising the electronic throttle failed its self-check – a computer fault, not… High P2111 Powertrain The throttle plate stayed more open than commanded – a real safety concern until you know why. High P2112 Powertrain The PCM asked the throttle to open, but it stayed shut – the engine can't get air, so it bogs… High P2149 Powertrain The shared supply to the second injector group dropped out, often an intermittent wiring fault… High P3191 Toyota · Powertrain The hybrid system spun the gas engine with its motor-generator, but the engine never fired up. High U0100 Network Another module stopped hearing from the engine computer on the CAN network. High
