P0206

Circuit Description
The PCM controls the fuel injectors by using an ignition feed and ground driver circuit within the PCM. The driver has the ability to detect an electrical malfunction in the ignition feed or ground circuit. If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #6, the ignition feed driver signals the PCM to set DTC P0206.

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 will illuminate the MIL during the second consecutive trip in which the diagnostic has been run and failed.
^ If equipped with traction control, the PCM will command the EBTCM via the serial data circuit to turn OFF traction control, and the EBTCM will illuminate the TRACTION OFF lamp.
^ 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 or fuel injector.
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. 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.
