did you check the resistor fastened to the duct work by the fan-has a wire running to it and a 2 or 4 little screws holding in place

Possible Service Engine Soon Light, Engine Stalling, or Hard Starting

Engine, May 18, 2009

RepairPal Expert Overview: The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.

Is it a 2.8 or 3.5 ?
It should be located in the exhaust manifold of your engine See number 10 on the diagram if this was helpful please vote thanks and god bless.





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.

probably a loose connector or if you have installed anything new maybe taken out a factory radio to put it a aftermarket one then that could be the problem vehicles these days run things like security and alarm systems through the radio. just check anywhere you have modified it or worked on it lately

first check the brake light fuse it powers the rear bulbs.remove and verify that all bulbs are working. note the wire colors going to the bulbs. replace as needed.next check the turn signal switch. if broken replace.sometimes switches break on the inside so measure from the power lead to the outputs. The wires going to the bulbs. easy because they are on the bulbs you checked.if you have towing package there will be a connector to hook up lights on the trailer. Inspect for bare wires or cuts in the insulation.good luck

could have a vacuum leak check all your vacuum line see if you feel or hear any air. do you have any engine light on if you do scan your engine get a code.

This happened to me. Problem is that the wiring and transercase ECM under the floor mats are not weather sealed. To fix the 4X4 ECM youll need to take up all the flooring and sound proffing. They hold a lot of water and never real dry out. Next to replace the ECM its easyest to take out the drivers seat. Four blots hold it to the floor. The black box under the seat (under the floor mates) is the ECM for the transfer case. Replace that and get the conections in the wireing dry and you should be good.
