P0139 Mitsubishi Delica Space Gear engine problem because the presence of voltage at the panel harness won't make the panel work if there is a bad ground connection. Since the instrument cluster is mounted in a plastic dash, a separate ground wire or ground circuit through the wiring harness is usually needed to complete the power circuit. Refer again to the wiring diagram to find the ground path, and then check it with your ohmmeter. Do not use a self-powered test light because it cannot measure resistance (any resistance will lower circuit voltage).

Mitsubishi Delica Space Gear P0139 OBD-II Diagnostic Powertrain (P) Trouble Code Description Mitsubishi Delica Space Gear car P0139 OBD-II Trouble Code The Heated Oxygen Sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. For optimum catalyst operation, the air fuel mixture (air-fuel ratio) Reason For Mitsubishi Delica Space Gear P0139 Code The reason of Mitsubishi Delica Space Gear P0139 OBD-II Engine Error Code is P0139 O2 Sensor Circuit Slow Response Bank 1 Sensor 2.

Mitsubishi Delica Space Gear P0139 Possible Solution :

In-line Ford engines, along with those of most other manufacturers, begin the numbering of cylinders at the front and proceed in numerical order toward the back. In the V-engine design, Ford follows a similar design with the number one cylinder at the front left of the engine. In the V-6 configuration, cylinder 4 is at the front right of the engine and in a V-8, cylinder number 5 is in that location. Other manufacturers sometimes use an alternating pattern in the V-engines.
