What to do if your injector code is p2149?

If the vehicle had only injector circuit codes for P0202 or P0207 (with bank shutdown P2146 or P2149), and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and install the injector harness support kit.

What does p0205 mean on a PCM?

P0205 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero.

How to tell if there is an open in p2149?

One test I like to do to determine quickly if there is an open within a particular wire which would help with code P2149 is to do a “continuity test”. Setting your multimeter to RESISTANCE (a.k.a.: ohm, impedance, etc.), touch one end to one tip of the circuit and the other end at the other tip.

What is the Mil code for a fuel injector?

Some examples of distinctions with injectors: Bank 1, 2, etc., paired injectors, individual injectors, etc. The ECM illuminates the MIL (Malfunction Indicator Lamp) with P2149 and/or related codes ( P2150, P2151) when it monitors a fault within the supply voltage to the fuel injectors and/or their circuits.

What does p2149 mean on a fuel injector?

P2149 Meaning The Engine Control Module (ECM) supplies voltage to each fuel injector on the high control circuits. The ECM energizes each fuel injector by grounding the low control circuit of the fuel injector. The ECM monitors the status of the fuel injector circuits.

What is the p2146 fuel injector group a circuit / open code?

The P2146 Fuel Injector Group A Circuit/Open code is active when the ECM detects a open or malfunction within the fuel injector’s supply voltage circuit. What is the severity of this DTC? Pretty severe I would say. In the field, we call a lack of fuel in the mixture being burnt, a “lean” condition.
