Google the code to see what it is & diagnose
the EGR System
There is no need to ever remove battery cables unless the
work you have to do would be safer doing so
Battery Cables & codes are not joined somehow
AFTER you diagnose a problem & AFTER to make the
required repairs & are sure your done,then you can clear ALL data
& road test until 7 of the 8 I/M Monitors run,leaving only the evap
to run days later.
Any time you remove a battery cable, you better know what will happen, or what features you will loose, or are not familiar with how
to restore them
Always use a code reader or scanner to clear DATA,your not clearing codes, your getting rid of valuable data only avail with
Ask yourself !
The key is off
How would changing plugs & wires be an issue?
How would the PCM know you worked on your car?
CODE P1441X2Well no one answered this i will. This is an Evaporative emission intake manifold Vacuum system problem. Which could have happened from a loose wire or bumpy road to a damaged EVAP canister or vacuum leak. This is a complicated unit to test for the NON mechanic. Tests on this system can run from a smoke purge test to chasing wires from the front to the rear of the vehicle. Great understanding of of this problem is needed. What has happened is the control module detects a vacuum during a non-purge condition. If you do not understand my previous sentence. This may be that time you want to put faith in your local garage. Some repairs to these system can be quite perplexing and frustrating and i have just began to describe what it is. Most times it is one of these, 1 Vacuum leak.2. EVAP canister. 3 EVAP purge solenoid. please rate my advice it is how i achieve my goals thank you.
PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS
Mine was doing this when I'd drive over bumpy roads. Noone could figure it out, till someone happened to check my battery cables. One of my battery cables was super loose and everytime I'd hit a bump, it would lose connection for a split second and shut the computer down, thus shutting off my Kia while driving.
Check the cables and make sure the cables are tight and the connections all look good.
Check Brake caliper and pads may need shims on pads, if its a rattling noise on bumpy roads calipers will rattle if brake clips or shims are missing. Car moving from left to right by itself could be a few things 1 Bad rack-andpinon mounting bushings 2. Bad inner or outer tie rods. 3. bad ball joints 4. uneven wear on tires. check all of the above and you will find your problem. Rpm guage not working more than likely is the cluster itself is going bad or malfunction. I wouldn't worry too much about since it just RPM.
