What is the fix for engine codes 181 186?
CODE 181, from service manual: DTC -- HO2S Orientation -- Fault Definition 181 -- Right or Rear -- Rich limit reached. Possible Causes: -- Fuel pressure -- Fuel injector -- Air intake -- MAP sensor -- Fuel injector electrical circuit -- Fuel filter -- Vacuum -- Air filter CODE 186, from service manual: G6 VISUALLY INSPECT MAF SENSOR Continuous Memory DTC 184 indicates MAF value is higher than expected. Continuous Memory DTC 185 indicates MAF value is lower than expected. NOTE: If further description is required for the In-Range Test, refer to Quick Test Appendix, $Section 5A$. l Key off. l Check for air leaks between IAC solenoid and MAF sensor. l Inspect MAF sensor for oil contamination. -- Excessive blow-by -- PCV malfunction (refer to $Section 14A$). l Are the above checks OK? Yes GO to $G9$. No SERVICE as necessary. CLEAR Continuous Memory (REFER to Quick Test Appendix, $Section 5A$). RERUN $Quick Test$.

P0300 Diagnostic Code - Random Misfire Symptoms. Engine may stumble or miss Engine may be hard to start you may notice no issues Cause Failing spark plugs or spark plug wir…es Bad coil or coil pack Failing oxygen sensor(s) Bad fuel injector or more than one Stuck exhaust valve Bad catalytic converter EGR valve or valve passage clogging Bad camshaft position sensor Bad PCM or ECM The Fix Best first action is a tune up, newplugs, wires, inspect all hoses and wire connections then reset thecode. If it returns you will need to narrow it down to a system, coilsand coil packs should be tested, catalytic converters for function ( doyou smell rotten eggs?). A misfire that jumps cylinders could indicate alean condition, do you have any other codes along with the 300? thiswill help clue you in to the source, check valve function to make surethey are opening and closing fully. This is probably pone of the mostdifficult codes to troubleshoot, so start with the basics and work yourway into the more expensive options, in many cases a good old tune upsolves the problem, back it up with a fuel system cleaning and see whereyou stand.
Replace the Oxygen Sennsor on the right side beind the Cat
The engine code P0355 is for a malfunctioning ignition coil. Thiscan be fixed by replacing the coil. It can be purchased at any autoparts store.
Trouble code P0205 means: Injector 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 Control. Not sure what it means or how to fix as of now. There is a TSB at the dealer for a software updat…e to the engine computer to correct those codes.
Trouble code P0203 means: Injector Circuit / Open - Cylinder 3. I think you need to replace the Injector on cylinder 3. . Remove the air intake snorkle that covers the #3 an…d #4 injectors. On the bottom of the snorkle you should find a metalic pad. Now, look at the wires that feed the #3 injector. If the injector is turned to just the right position, the wires can rub on the metalic pad. If it wears enough it will rub through the wire insulation and you will be able to see copper stranded wire as a result. To repair this, place some automotive-type silicone gasket maker (in a tube), covering the bare wire and then allow to dry for 24 hours. Also, turn the injector 45 degrees (either right or left) to move the wires away from the metalic pad. This will effectively lower the wires so that they won't rub. Another thing that could be done is to add a 1/4" spacer under the snorkle bracket on the front locating stud. This will also increase the space between the bottom of the snorkle and the #3 injector wiring harness/connector. If this doesn't fix the problem then it's probably your injector.
Trouble code P0171 means: Fuel System Too Lean - Bank 1
Check your coolant overflow reservoir, if it is to the marked line you should take it to a certified mechanic as the problem maybe a faulty sensor. If the reservoir is empty t…han fill to the line marked then remove negative terminal from battery and turn on head lights for 15 minutes. Reattach negative terminal and test drive. If CHECK ENGINE light comes back take your vehicle to a certified mechanic.
With a p0455, the most common repair is to: . Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back. . Otherwise, replace th…e gas cap, and/or . Inspect the EVAP system for cuts/holes in tubes/hoses that run from the fuel tank to the engine (you may hear a vacuum noise or smell fuel), repair if necessary
P0440 sets when the evaporative emission system large/medium leak monitor test fails. Normally meaning there is a leak in the system. This can happen from a loose or not seali…ng gas cap, solinoid valve not working or not sealing, or a brocken/cracked emission hose. Best bet is to do a visual inspection of the evaporative emission system and replace anything that is broken or unhooked. If you can find anything take it to a repair shop and have a evap system leak test performed. Most new OBDII car can be forced to run the monitor test with a handheld scan tool with the correct software installed.
Diagnose the problem and fix it
OBD II P0420, Catalyst System Efficiency Below Threshold. In some cases, there may be some performance problems noticed by the driver such as a lack of power from a restricted… and/or damaged Catalytic Converter. Common Problems That Trigger the P0420 Code . Inefficient Catalytic Converter(s) . Defective Front or Rear Oxygen Sensor(s) . Misfiring engines Common Misdiagnoses . Oxygen Sensors good-day ! hope this helps !
Check for vacuum leaks and good electrical connection at the EVAP vent solenoid
This code is set because there is a leak in the evaporator emission system. First check to make sure the gas cap is not loose.
what car is it on... year make model... engine size/ auto or manual trans. That's a VW only code-idle speed control low input- problem with tps on throttle body most likely…. R&R.
