I'll try these out tonight,and could possibly be the ignition switch cause I just replaced it with a napa part, and Me and napa dont get along, but it's the only way for me to get cheap parts because I use my work account. I also replaced the ignition starter switch. The only thing is some people are saying ignition 0 is suppose to be hot, others are sayin its not suppose to be, so I guess I'll try both routes
and as far is p1671 its just a mil light not showing up, its still my only code
Heres the alldata on it:
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. DTC P1671 set indicates an improper voltage level on the output circuit that controls the Malfunction Indicator Lamp (MIL).
Conditions for Setting the DTC
Ignition is ON.
An improper voltage level has been detected on the output circuit which controls the MIL.
Above conditions for at least 30 seconds.
Action Taken When the DTC Sets
The PCM will illuminate the MIL during the first trip in which the diagnostic test has. been run and failed.
The PCM will store conditions which were present when the DTC set as Freeze Frame and Fail Records data.
Conditions for Clearing the MIL/DTC
The PCM will turn the MIL OFF during the third consecutive trip in which the diagnostic has been run and passed.
The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
The DTC can be cleared by using a scan tool.
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 digital multimeter connected between the MIL control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the MIL. A change in voltage will indicate the location of the malfunction.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
Test Description
Number(s) below refer to the step number(s) on the Diagnostic Table:
Normally, ignition feed voltage should be present on the control circuit with the PCM disconnected and the ignition turned ON.
Checks for a shorted component or a short to battery positive voltage on the control circuit. Either condition would result in a measured current of over 500 milliamps. Also checks for a component that is causing an open circuit while being operated, resulting in a measured current of 0 milliamps.
Checks for a short to voltage on the control circuit.
This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is being replaced, the new PCM must be programmed.
