This is a transmission code. Not good. Some of the Accord transmission's had a quiet recall. call your local dealer with the VIN # to check.
Question Answered: Power window does not operate
April 07, 2011, 05:16 PM
You will have to remove the door panel to access the window motor. There are two wires going to the motor. You will need a test light, check for power at the motor when pressing the window switch up or down, if you see power. The motor is the problem.
Question Answered: IAC/Whinning noise/ECS leak
April 07, 2011, 05:13 PM
My first recommendation would be is to make sure that the technician is using factory parts only in reguards to the IAC.
The whinning noise does sound to me like a IAC motor problem. Also check for any sort of restrictions in the air box leading up to the intake.
If you have a very small EVAP leak (P0446) then the IAC will NOT fix that problem. The most common fix for a small EVAP leak is the gas cap.
Question Answered: Running Hot

If the system is full of antifreeze, drive the vehicle for about 10-15 minutes on the highway. Then reinspect. CAREFULLY feel the upper and lower radiator hoses, they should feel abouth the same temperature. If not suspect a flow problem (water pump, stuck thermostat, headgasket causing air pockets). Also feel the radiator fins, it should be aroundf the same temperature all around. If it only runs hotter at highway speeds, suspect a clogged radiator.
Question Answered: not passing smog
April 07, 2011, 04:53 PM
If you failed the smog test because the readiness moniters have not run, then yes the technician is right. You will need to drive the vehicle a specific way meeting all of the parameters. Google it.
But if you failed because you have current or pending codes, then those will need to be addressed first.
Question Answered: Engine

We use GM top engine cleaner for best results in removing carbon buildup on the back of valves. The procedure is to lrun the engine at 2500 rpm's, insert the fluid by removing a vacuum line that leads into the intake manifold, the let the fluid run into the intake until it stalls. Let it sit like this for half an hour to let the cleaner really loosen up the carbon. Then restart the engine, it will run rough at first and will probably have a check engine light on that will need to be cleared. And it WILL SMOKE A LOT. let the engine idle for a good 20 mins then take on a long road test.
Question Answered: check abs system and check traction lights comes on
April 07, 2011, 04:38 PM
The ABS and Traction Control system are the same. When these lights are illuminated that means the ABS system has detected a fault. It deactivates the ABS and Traction control until it no longer sees the fault.
You will need tp have the ABS computer scanned to identify the fault code, then follow the apropriate flow chart to diagnose the problem.
Question Answered: code 2 / bank 2 exhaust sensor / oxygen sensor
April 07, 2011, 04:34 PM
On a V motor (6 or 8 cylinder) Bank 2 refers to the side of the motor opposite of bank 1. Bank 1 is always located on the same side as cylinder #1.
Question Answered: low idle
April 07, 2011, 04:26 PM
The idle is conttrolled by the IAC motor (idle Air Control). The iac is a valve that adjusts airflow. What you have to do is remove the iac, clean the housing and throttle plates of carbon, then reinstall. Then you have to set the minimum aire rate. All these means is position the iac in the fully extended position, disconnect it so the ecm will not change its position, then adjust the idle to around 550 rpm's. If you had a scanner the counts should be below 20 which indicates the postion of the iac.
I would start with this first. if you suspect the egr valve is not closing as it should at idle, then remove it and plug the vacuum leak created from the missing egr valve. If the idle goes to normal, suspect faulty egr or it is being commanded incorrectly from the ecm to open.
