P0206

Circuit Description
The powertrain control module (PCM) controls each fuel injector separately through a ground driver circuit located within the PCM. The PCM monitors the driver circuit and has the ability to detect an electrical malfunction. If the PCM detect an electrical malfunction in the fuel injector circuit for cylinder #6, DTC P0202 is set.

Conditions for Running the DTC
The engine is running.

Conditions for Setting the DTC
^ The PCM detects an electrical malfunction on the injector circuit for engine cylinder #6.
^ The condition is present for at least 30 seconds.

Action Taken When the DTC Sets
^ The PCM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the diagnostic test has run and failed.
^ If the electrical malfunction could lead to possible catalyst damage, the PCM immediately flashes the MIL while the fault remains at catalyst damaging levels.
^ The PCM disables TCC operation.
^ The PCM stores the conditions which were present when the DTC set as Freeze Frame and Fail Records data.

Conditions for Clearing the MIL/DTC
^ The PCM turns the MIL off during the third consecutive trip in which the diagnostic has run and passed.
^ The history DTC clears after 40 consecutive warm-up cycles have occurred without a malfunction.
^ The DTC may be cleared using the scan tool Clear Info function or by disconnecting the PCM battery feed.

Diagnostic Aids
The misfire history counter may be useful in determining which injector circuit is malfunctioning. If DTC P0300 is set, look at the Misfire Hist # display for each cylinder. The largest value stored in the misfire history counters indicates the location of the malfunctioning injector circuit or injector.
Inspect for the following conditions:
^ A faulty connection at the PCM or the fuel injector. Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connections.
^ Inspect the wiring harness for damage. 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.
4. Checks for malfunctioning fuel injector control circuit or ignition feed wiring.
9. Checks for a malfunction in the fuel injector ignition feed circuit.
10. Checks for a short to ground in the injector control circuit.
11. Checks for an open in the fuel injector control circuit.
18. 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.
