Pontiac odm codes

The PCM uses output driver modules (ODMs) to control many functions of the engine, and the transaxle. The ODMs supply the ground path for the PCM controlled device when the PCM commands the device ON. Each ODM is able to control several outputs. Unlike the quad driver modules (QDMs) used in earlier model years, the ODMs are able to diagnose each output circuit. The PCM monitors the ODMs for circuit conditions that are incorrect for the commanded state of the ODM. If the PCM detects an improper circuit condition in the ODM that controls suspension Lift/Dive, DTC P1652 will set. This something you need to take to the dealer !

DTC P1655 Evaporative Emission (EVAP) Purge Solenoid Control Circuit !
Output Driver Modules (ODMs) are used by the PCM to turn on many of the current-driven devices that are needed to control various engine and Transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding on. Unlike the Quad Driver Modules (QDMs) used in prior model years, ODMs have the capability of diagnosing each output circuit individually. DTC P1655 set indicates an improper voltage level has been detected on ODM B output 5, which controls the EVAP purge solenoid.
You could have a wiring problem ,or the purge solenoid or the driver in the PCM ! More then likely it's the EVAP purge solenoid !

DTC P1676 Evaporative Emission (EVAP) Purge Solenoid Control Circuit
DTC P1676 set indicates an improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
Circuit Description
Output Driver Modules (ODMs) are used by the PCM to turn on many of the current-driven devices that are needed to control various engine and Transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding ON. Unlike the Quad Driver Modules (QDMs) used in prior model years, ODMs have the capability of diagnosing each output circuit individually.
Diagnostic Aids
Check for the following conditions:
?€¢
Poor connection at the PCM.

Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.

?€¢
Damaged harness.

?€¢
Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.

it is not a engine code it is ABS code C1222 Right Front Wheel Speed Sensor Input Signal is 0 history

looks like all 4 brakes need checked..

MAP SENSOR LOW VOLTAGE!!

P0650

Description
Malfunction Indicator Lamp (MIL) Control Circuit Output drive moduels (ODM's) are used by the powertrain control module (PCM) to turn on many of the current-driven devices that are needed to control various engine and transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device whish the PCM is commanding ON. Unlike quad diver modules (QDM's) used in prior model years, ODM's have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an impropervoltage level on the output circuit that control the MIL.

Huh??? If there is a code P1655 then tere IS a DTC! DTC means Diagnostic Test Code. The DTC you have is P1655. So, I am not sure exactly what you are trying to say here.

DTC P1655 is a "Vehicle Specific" code. The only way to know for sure what the problem is, would be to look the code up based on the specific Year, Make, Model and Engine Size of the vehicle we are talking about.

For MOST GM vehicles, the code description is P1655 "EVAP Purge Solenoid Control Circuit".

I can't verify this without knowing what you are working on and cannot give yopu any specifics on how to repair it for the same reason.

you will have to go get your computer reflashed or possibly buy a new one whatever is cheaper
