Default P0..NO!!NO!!NO!!! Error Codes

ARGH!!! Just got the engine management light on, did the key dance and the following have come up:
P0403 Exhaust Gas Recirculation (EGR) Solenoid Control Circuit
P0703 Brake Switch Circuit Malfunction
and ending with
P1685 Driver 5 Line 5

This all makes sense as I did notice some exhaust fumes every now and then and the hand brake is very poor. My question, should I panic and think the worst as in this is going to cost me thousands and to drive it would make the car explode or is it a case of I can drive it but will probably get worse so get it looked at soon?

Hate this as I'm a totally newb and freak out quite easily when life isn't rose tinted mechanically!!!

well with any problems you get with mechanically minded items driving it could potentially get worse and cause more problems with other items. how serious this is I am not sure as ive not run into these problems myself. bottom line advice would be get it checked out as anything to do with brakes is quite a serious topic and something you wouldn't want to chance

Brake circuit means electrical. So I would check the brake switch on the brake pedal. Check the connector or harness that goes to the solenoid (egr) fuses ans so on. Not sure what the other code is for.

i fixed my EGR code by changing the EGR transducer instead of buying the whole valve. i bought this for $33. it seems the electronics are what fails, not the valve itself. i'm not sure which PT you have, so your part may be different. i have a US model 2002 with a 2.4

From PT D0-It-Yourself.net:

P1685 Skim Invalid Key - The engine controller has received an invalid key from the SKIM.

I would not mess with the SKIM. The issue with the SKIM may be tied to the faulty TCM. The TCM is integrated into one module, called the PCM.

SKIM Operation

When the ignition switch is moved to the RUN position, the SKIM transmits an RF signal to the transponder in the ignition key. The SKIM then waits for a response RF signal from the transponder in the key. If the response received identifies the key as valid, the SKIM sends a “valid key” message to the PCM over the PCI bus. If the response received identifies the key as invalid or no response is received from the transponder in the ignition key, the SKIM sends an “invalid key” message to the PCM. The PCM will enable or disable engine operation based upon the status of the SKIM messages. It is important to note that the default condition in the PCM is “invalid key.” Therefore, if no response is received by the PCM, the engine will be immobilized after two (2) seconds of running.


Me: Unless your having problems with the key or fob or anything to do with it, I'd take off the negative battery cable for 5 minutes. Step on the brake pedal to get rid of any residual charge. Put it all back together and take a run. This resets the computer and gets rid of the stored codes. See what codes come back and if any were old codes stored in the computer before this latest event.

Thanks for the replies all. Just took it for a short drive and the light has gone out. I'm guessing the best thing to do now is ignore it and carry on as if I'd never seen it!!

In all seriousness I will get it looked at as the handbrake needs to pulled to the max for it to be effective. I got this car reasonable cheap so I've mentally put aside a few hundred for repairs........just didn't want them this soon.

Oh and CREWZIN I have to find the battery first....rumour has it it's under the passenger seat on the diesel!!!

Yes, on the diesel, we've been told to look under that seat for the battery
