At my wit's end with Check Engine Light- PU140 code
At my wit's end with Check Engine Light- PU140 code
p0140 = "Secondary Air Injection Pump" with my 2004 Coupe
I've searched this website high and low. I've replaced the blue check valve, I've replaced the ENTIRE PUMP. It's been in the shop 4 times now. Checked by 2 seperate mechanics (including a Chrysler dealership). All they do is check the pump to ensure it is working, clear the code, and say it's good. The check engine light comes back on after a day or 2 after clearing the code.
I have NO idea what to do next. The last mechanic literally told me "The pump works, there's nothing wrong with the Secondary Air Injection System. It has to be an electrical problem that is setting off the code."
The Chrysler dealership was also no help, saying "there's nothing wrong with it". Even when I INSISTED that the code will come back on they said that it wouldn't. And, IT DID COME BACK ON!
Here's the kicker. I have to sell the car, because we ordered a new Dodge Dart from the factory. I've had several people look at the car and will not buy because of the check engine light. The only code that comes up when you run a OBD Diagnostic computer is PU140. As many times as I explain that I've ran the car for a year and a half with the engine light on, and it's confirmed by 2 mechanics that there is literally nothing wrong with the pump, no one wants to buy it.
I'm about to rip the dash apart and pull the bulb for the check engine light. Please, if any of you have ANY ideas, PLEASE let me know.

Re: At my wit's end with Check Engine Light- PU140 code
Well, it probably has nothing to do with any air injection pump... or anything to do with any air, or injection, or pumps...
I got the code because of a bad RCM... if you can solder, give it a shot

Sorry, not sure what you were going for here but I will say that I had the check engine light with the 140 code with no other issues/starting problems.. and the RCM fixed it
Re: At my wit's end with Check Engine Light- PU140 code
The joints showing in his pic.. Mystery no Start connections to check.. Not where the air pump relay is soldered down.. And yes I am agreeing it very well could be the RCM causing the code.. just not the specific area on the board he's inspecting..
Clear as mud now?

Think you are referring to
P0410 = Secondary Air Injection System Malfunction
My "check engine light" comes on every once in awhile and I simply reset it with my UltraGauge OBDII Scan Tool
connected inside my car anyway.
Car runs fine and the air pump works perfectly so I don't really care about the light

Just one of those little things huh.. LOL. My cats were "cored" by the previous owner and about once a month pops up the two codes on them. Figure she must be right on the edge, and have noticed lower quality gas will pop the cel in about a day after gassing up. Blue toothe elm adapter and Torque pro makes it short lived though.
