Code P2247


DTC P2247: Front A/F Sensor (Bank 2, Sensor 1) VCENT Line High Voltage

NOTE:
Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
Information marked with an asterisk (*) applies to the front bank (Bank 2).
Turn the ignition switch ON (II).
Clear the DTC with the HDS.
Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on, then let it idle for 2 minutes .
Check for Temporary DTCs or DTCs with the HDS.
Is DTC P2243 and/or P2247* indicated?

YES - Go to step 5.

Does the screen indicate PASSED?

YES - Troubleshooting is complete.

NO - If the screen indicates FAILED, check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 18 and recheck.

Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.
Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?

YES - If DTC P2243 and/or P2247* is indicated, check for poor connections or loose terminals at the A/F sensor (Sensor 1) and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.

The check engine light came on message was in reference to the TAC?


Hi there:
DTC P0638 - Throttle actuator control range/performance
The engine control module (ECM) opens the throttle blades by applying a pulse width modulated voltage to the throttle valve motor. The ECM reverses the polarity on the throttle valve motor control circuits in order to close the throttle blades. The ECM increases the pulse width as necessary to open the throttle blades. The ECM monitors the throttle position (TP) sensors 1 and 2 to determine the actual blade position. If the ECM detects the required pulse width modulation (PWM) to move the throttle blade exceeds a predetermined value, DTC P0638 sets.

According with recalls...
REPAIR ACTION:
* Replace the Throttle Position Sensor (TPS)
* Perform the ECM software update.

NOTE :Always perform a GDS ECM Update by Automatic Mode first as it performs error checking to ensure the correct data is flashed into the vehicle. Always select the latest available ECM Update event data at time of your update.

Steps to replace the ecm. do I need to unhook the battery, or anything. After it is replaced, is there any other steps like resetting anything?


Replacing and ECM is a farily involved job which will require reprogramming the replacement ECM to match the vehicle that it is installed in. Dealerships and a few independent service facilities are set up to do the reprogramming but the unprogrammed ECM may not even be able to start the vehicle until programmed so it's not a DIY kind of project. It's RARE that a vehicle needs the ECM replaced as there are a quite a few problems that can mimic a bad ECM and often an ECM problem can be fixed with a reflash update of the software. Hope this helps and good luck!

Light from the engine is turn on. Fix the problen but light will not go off.


Hello.
If you, or a friend did the repair and don't have the equipment, ( like a dealership ), to update the ECM, ( Electronic control module, also refered to as the computer ), you will most likely need to drive the car several times to allow the ECM to recognize that the repair has been made.

For the ECM to update itself it needs, what is refered to as, " two drive cycles ".
If the repair you made was the only thing it needed the ECM will update itself, it just takes a little time.

I hope this helps you!

The battery goes dead in my 2006 cady xlr after not driving it for 2 to 3 weeks, is this normal?


There Are 2 Software Updates That You Can Get From The Dealer (If Not Already Installed), One Is An Update For The ECM, The Other Is An Update For The RCDLR.
TSB07-06-03-001B (RCDLR)
The Other For The ECM Is An Unpublished Document
You Will Generally Be Looking At Paying 1H For Programming 2 Modules.
After This Have The Battery Properly Charged & Load Tested.
