P0406 Powertrain The EGR feedback sensor is reporting close to 5 volts or more, above anything a working sensor… Low P0410 Powertrain The cold-start air pump system that helps heat the catalytic converter didn't pass its… Low P0411 Powertrain The air pump runs at cold start, but the right amount of air isn't reaching the exhaust. Low P0412 Powertrain The ECU found an open or short in the circuit of the valve that routes air from the pump into… Low P0418 Powertrain The ECU sees a fault in the relay circuit that switches the secondary air pump on and off. Low P0421 Powertrain The close-coupled warm-up catalyst on bank 1, right behind the exhaust manifold, isn't working… Low P0431 Powertrain On a V6, V8 or flat engine, the warm-up converter on the side without cylinder #1 is no longer… Low P0440 Powertrain Catch-all EVAP code: the system failed its self-check. Start with the gas cap, then check hoses… Minor P0441 Powertrain The ECU opened the purge valve but saw the wrong flow: too little, too much, or at the wrong… Low P0443 Powertrain The ECU detected an electrical fault in the purge solenoid circuit: open, shorted or a bad… Low P0444 Powertrain The purge valve circuit is broken somewhere: unplugged connector, open coil, broken wire or no… Minor P0447 Powertrain The canister vent solenoid circuit is open, so the ECU can't close the vent to run its leak… Minor P0449 Powertrain Electrical fault on the canister vent solenoid circuit, a staple on GM trucks with the solenoid… Low P0450 Powertrain The fuel tank (EVAP) pressure sensor failed a self-check, so the ECU can't trust its leak tests. Minor P0451 Powertrain The tank pressure reading is electrically fine but doesn't make sense: offset, stuck, noisy… Minor P0452 Powertrain The tank pressure sensor signal is stuck near 0 volts, lower than the sensor can physically… Minor P0453 Powertrain Tank pressure signal pinned near the top of its range: lost ground, short to voltage or real… Minor P0460 Powertrain The engine computer gets no usable fuel level signal – often a tank-top connector or the sender… Low P0461 Powertrain The fuel level reading doesn't change the way fuel use says it should – usually a worn or stuck… Low P0462 Powertrain Fuel level signal voltage stuck near zero – usually a shorted sender or a signal wire rubbing… Low P0463 Powertrain Fuel level signal reads like an open circuit – most often a corroded tank-top connector… Low P0480 Powertrain Fault in the circuit that switches the main radiator fan – the engine can overheat in traffic. Moderate P0481 Powertrain The second fan output – a second fan or the high-speed stage – has a circuit fault; A/C suffers… Low P0496 Powertrain Vapor is being drawn into the engine while purge is commanded off: almost always a purge valve… Low
