P1694 Fault In Companion Module No CCD/J1850 messages received from the powertrain control module-Asian transmission. P0141 (M) O2 Sensor Heater Circuit (Bank 1 Sensor 2) Oxygen sensor heater element malfunction. O2 sensor voltage greater than 3 volts for 60 to 240 seconds. P0455 (M) Evaporative Emission Control System Leak Detected (large leak) A large leak has been detected in the evaporative system. See TSB 25-001-02. Also, possible faulty or loose gas cap. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.
