This is due to an abnormal electrical noise within the engine harness of certain vehicles. This condition can be prevented or corrected by installing the throttle body harness (with diode) as described in this service bulletin.note:the throttle body harness (with diode) should only be used to correct dtcs p0123 and/or p0222 that were set after the throttle body was replaced. Vehicles that have stored dtcs p0123 and/or p0222 without a throttle body replacement should be diagnosed and repaired according to the workshop manual, not this service bulletin.
