The cost to fix a P0013 code depends on the type of vehicle and the issue. – The exhaust solenoid costs between $20 and $60, while labor costs are in the range of $75 and $150. – The camshaft position sensor costs between $40 and $60. The price of a mechanic is between $100 and $130. lots of odd things can happen in fuel injected cars sometimes the reverse of what you may expect. typically a malfunctioning O2 sensor can affect adjustments to TIMING thus for same accelerator position engine revs can rise/fall or become unstable just because O2 sensor is duff. if O2 bad poor acceleration/easy stall is definitely likely due to fluctuation in timing. can also cause pinking SOURCE: citroen c5 esp/asr system fault Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL, CEL and BCM faults and others) as long as the light is on. P2202 is a diagnostic trouble code (DTC) for "Nitrogen Oxide Sensor (NOx) Sensor Circuit Low Input Bank 1". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light Do you have any other outlets in your area that would test the battery for you. Given the age of the battery it could well need changing. Could you borrow a charger and try that. It could be on a battery of that age that the load is too much and it's not holding it's charge. I'm no expert either but I'd still suspect the battery. Tue Oct 25 2011, 04:16pm. Member No: #16758. Joined: Dec 08 2010.

Doesn't seem too expensive in the grand scheme of things. TG, referring back to the link to the Citroen specific OBD2 pinout in your post of Thurs 13th Feb, the PIN 14 (CAN Low) has a description “J-2284 / K-Line Central door locking system”. I only just realised the potential relevance of this – or it could be just coincidental. 4DNC.
