Hi, thank you for choosing Just Answer!
P0203-INJECTOR # XXXXX CONTROL CIRCUIT
P0204-INJECTOR # XXXXX CONTROL CIRCUIT
etc., etc., Get the idea?
You also mentioned... E0153? This is incorrect format.
The letters should be B, C, P, and U
If it is giving you a code starting with an E, then the computer is faulty.
Those codes are circuit problems. Changing the injectors won't necessarily solve the problem.
The E code is what has me worried, because the computer is the main part of the injector circuit.
Please tell me the 'E' thing was only a typo...???
Did this problem just start one day when you cranked it up? or after running for only a few minutes...???
O2 sensor, yes...But it is a code about contamination on this particular engine...
Might start with checking that fuel filter...
If the injectors are stuck open, then it looks like someone has contaminated the fuel system. The way to check this is to hook a fuel pressure gauge to the engine, and pressurize the system. Pinch off the return line to the pump, and see if it holds pressure. If it doesn't hold pressure, then it is very possible that the engine will need some new injectors.
Let me know what you find!!!
