Need help with CTD trouble codes - Pirate4x4.Com : 4x4 and Off-Road Forum

willyquasar · 07-26-2007, 06:43 PM

I just finished changing the water pump on my 03' CTD. Started it and the check engine light came on. Did the on/off/on/off/on/off and got some codes.
P 2509
P 0073
P 0107 - I found this one. It said low voltage to MAP sensor. WTF???
Anyone know the other codes?
Thanks...

I did a search on TDR and it sounds to me like you may have got some water or antifreeze on some electrical connectors. The third gen is prone to getting water in the connectors aparently.

2509-ECM/PCM power input signal intermittent
0073 Manifold absolute pressure low

Thanks... I was wondering if I had got some water on something.

Another thing you may want to check is your MAP sensor...they get dirty really quick. If you have a exhaust brake it'll get dirty even quicker.

I kept getting an overboost code. I checked with cumminsforum.com, they said to just pull the sensor spray the lil' bastard with carb cleaner and no more codes.

Hope you get it fix!
