SOURCE: i dont know what that code means to identify problem

Get the info from who ever pulled the code. No one would own a scan tool without a code book. I know everyone wants to repair things them self and save money ,but you need a lot of knowledge and tools to work on todays vehicles. You will end up putting a part on and still have the same issues. Codes do not tell you what's wrong or what to repair. Just a starting point in the diagnostic process.

DTC P0135
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensor to reach operating temperature. Voltage is provided to the heater by the ignition 1 voltage circuit through a fuse. With the engine running, ground is provided to the heater by the HO2S heater low control circuit, through a low side driver within the powertrain control module (PCM). The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM determines the temperature by measuring the current flow through the heater and calculating the resistance. Based on the resistance, the PCM can predict the sensor temperature. The HO2S 1 uses pulse width modulation (PWM) to control the heater operation. The HO2S 2 simply uses ON/OFF commands to control the heater operation. For diagnosis, the PCM monitors the heater current with the engine running. The PCM also calculates the heater resistance on a cold start. Both diagnostics will only run once per ignition cycle.

If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0135 sets for HO2S 1.

Po455 code meaning evap large leak detected on my 2004 colorado.trying to get it too reset.found the gas cap off..maybe possible problem.book says a couple driving trips to reset.is this right?can i just...


Well, yes, the gas cap off can cause this problem. The quickest way to erase the code is to use an OBD-II Scanner borrowed from your local autozone or advance auto. The erase code button is used to accomplish the task.. pretty routine.
