P0209 Injector 9 Control Circuit

* 2509 code is set when one or both batteries are weak or dead.
Or
P2509 has a TSB 18-001-07 which is a flash
This is where I got the 2509 info:

* The rest came from Allpar.
P1740 Torque Reduction Signal Circuit: Overdrive and TCC Solenoid Rationality

Al Steier wrote that P1740 is a Chrysler-only code. On RE transmissions, the computer was looking for a drop in engine speed after the overdrive solenoid or torque converter clutch were applied; since lockup comes in fourth gear, it doesn’t know whether the rpm drop is due to moving to overdrive or locking the torque converter. If a truck shows P1740 is probably has one of two problems: a bad overdrive or torque converter solenoid, or bad torque converter material so that the torque converter clutch cannot hold lockup.

Is a person a failure for doing nothing? Or is he a failure for trying, and not succeeding at what he is attempting to do? What did you fail at today?.

Injector 9? Seriously?

I got that from the code page.

»www.obd-codes.com/p0209
quote:
What does that mean?

P0209 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. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.
Potential Symptoms

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

Could be that the batteries popping like they did burnt a few wires.

code quote, you'll have to scroll to see the code.
