Expect stalling or a crank-no-start. High P0339 Powertrain The crank signal drops out for moments at a time. Classic sign: stalls when hot, restarts once… High P0340 Powertrain The computer lost the camshaft signal on bank 1. Expect long cranking, less power… Moderate P0400 Powertrain EGR flow doesn't match what the ECU expected, and the code doesn't say whether it's too much… Low P0421 Powertrain The close-coupled warm-up catalyst on bank 1, right behind the exhaust manifold, isn't working… Low P0463 Powertrain Fuel level signal reads like an open circuit – most often a corroded tank-top connector… Low P0506 Powertrain The engine idles below the computer's target even with idle air opened up – usually a gummed-up… Low P0700 Powertrain The transmission computer found a fault and asked for the check engine light – read the TCM… Moderate P0715 Powertrain The transmission computer has lost a reliable input-shaft speed signal, so shifts get harsh… Moderate P0730 Powertrain The transmission computer sees input and output shaft speeds that don't fit the gear it… High P0744 Powertrain Lockup control drops in and out: an intermittent TCC circuit, or on some makes a lockup… Moderate P0746 Powertrain Solenoid A doesn't control pressure as commanded: harsh or soft shifts, or limp mode. Moderate P0776 Powertrain Pressure control solenoid B isn't delivering the pressure the TCM asks for – harsh or slipping… Moderate P0841 Powertrain Pressure sensor or switch A reports a value that doesn't fit the gear or pressure the TCM… Moderate P1217 Nissan · Powertrain Nissan's ECM saw engine coolant get hotter than it should, usually because the radiator fan… Critical P1272 Nissan · Powertrain The front air/fuel ratio sensor on bank 1 isn't sending a usable, moving signal to the Nissan… Moderate P1273 Nissan · Powertrain Nissan's ECM sees the front air/fuel ratio sensor on bank 1 reading lean for too long and flags… Low P1320 Nissan · Powertrain The Nissan ECM isn't seeing the ignition primary signal it expects while the engine cranks… Moderate P1444 Nissan · Powertrain Nissan's ECM sees fuel vapor flowing to the engine while the purge valve is supposed to be shut.
