RE: 2V Engine codes

what are the short and long trims at? the 1131 and 1151 are generic lean codes and you will usually fint the trims adding fuel at idle or off idle if the trims go over 10% you can set p0171/p0174 or these codes

P0135 Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P0155 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1)
P1131 Lack Of HO2S11 Switch - Sensor Indicates Lean
P1151 Lack Of HO2S21 Switch - Sensor Indicates Lean

Any one had these?

[/align][/align]The P0135 and P0155 codes are telling you that the O2 sensor heaters on both front sensors are not working--the P1131 and P1151 codes are the result of this. [/align][/align]Whennarrow-band O2 sensors are cold they behave electrically like large value resistors, instead of generating a voltage; this low to no voltage signal is interpreted by the PCM as "running lean" and out of its control.[/align][/align]Click here to see the possible causes...[/align]
