P2110 Powertrain The PCM is capping engine speed with fuel cut-off because it can't fully trust or close… Moderate 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 P2118 Powertrain The throttle motor is drawing more or less current than the PCM expects to hold the plate where… Moderate P2119 Powertrain The throttle plate isn't reaching the position the PCM commands, or won't spring back to its… Moderate P2120 Powertrain The PCM lost a usable signal from the main gas pedal sensor, often only for a moment. Moderate P2121 Powertrain The main gas pedal signal stays within normal voltage but moves in a way a real pedal can't. Moderate P2122 Powertrain The main gas pedal sensor reads close to 0 volts, below anything a working pedal produces… Moderate P2123 Powertrain The main gas pedal sensor reads near its full 5-volt supply or higher, even with your foot off… Moderate P2125 Powertrain The PCM lost a valid signal from the second, cross-check sensor in the gas pedal. Moderate P2127 Powertrain The second gas pedal sensor dropped below its minimum voltage, so the PCM can't verify pedal… Moderate P2128 Powertrain The second gas pedal sensor reads above its allowed maximum, so the pedal position can't be… Moderate P2135 Powertrain The two position signals inside the throttle body disagree, so the PCM can no longer trust… Moderate P2138 Powertrain The two sensors in the gas pedal report different pedal positions, so the PCM limits throttle… Moderate P2176 Powertrain The PCM hasn't stored where the closed throttle sits, usually after a battery disconnect… Low P2177 Powertrain Bank 1 goes lean once the engine is above idle, so the PCM keeps adding fuel at cruise… Moderate P2178 Powertrain Above idle, bank 1 carries more fuel than the PCM asked for, and pulling fuel out no longer… Moderate P2181 Powertrain The engine isn't warming up or holding temperature the way the computer's model says it should. Low P2187 Powertrain Bank 1 runs lean at idle but recovers once rpm rises, the classic fingerprint of unmetered air. Low P2188 Powertrain At idle, bank 1 gets extra fuel from somewhere the PCM doesn't control; above idle the mixture… Moderate P2195 Powertrain The front O2 or air-fuel sensor keeps reading lean while the rear sensor shows the engine isn't… Low P2196 Powertrain The front sensor on bank 1 keeps claiming rich, so the PCM strips out fuel the engine actually… Low P2197 Powertrain The upstream sensor on the bank without cylinder 1 reads lean while the other checks say that… Low P2198 Powertrain Bank 2's front sensor keeps claiming rich, so the PCM leans out that side of the engine more… Low
