Thread: Back to the code game

i did check the fuse this morning. No luck, it was fine but i replaced it just in case. but no change. Will have to check wires. I guess i could change the MAF with other car and see if there is any change. then i will know its the wires.

Guess who has a NEW CODE!!
yup this guy

P0140 says o2 sensor circuit no activity detected bank 1 sensor 2

Whats this all about?
Im about to think this dam car is like... what code can i throw at him today??

New day, New code
P0142 02 Sensor Heater Circuit Bank 1 sensor 2 ....

Another Question. I had some space to WOT on way home. Notice boost gauge only goes to 5/8 full. Also i think i hear the rock sound from supercharger. I have changed the coupler this summer but with all the missfire and Stalling. Could that need to be replaced again?

Back to the MAF, i have changed it with other car, Both had no change at all so i think is has to be the wires? if not wires. what eles? Also noticed my fog lights dont work. the light on dash is out. Could there be a short? I have to change the Front driver CV axle, Any videos or links would help a ton. Ordering parts today. Also Heat is only blowing hot out Two (of three) vents in middle. and cold on two outsides. Where is a diagram on that isssue too.... About to go put it on jack and check wires and maf and O2 sensor. would all these be a ECm issues?

Fog lights all set now, looked at all Fuses, under hood and behind dash.Every one looks good.

check the fuse box #21. it powers the maf and o2 sensor.

or the o2 wires are melted or the maf wires are cracked up.

I jacked up the front of car. put hands at 12 and 6 and driver side did wiggle. Now at first i was thinking it was CV axle. but after taking tire off and wiggling around it looked to me to be a bad bearing. Also my ABS light is on. I have changed the wheel bearings on my old gtp (2000) but its was different issues so now im not sure. if i put my hands at 9 and 3 and wiggle. it moves. but not as bad. There is also a shimmy when Accl. but fine when off the gas. so maybe CV AXLE?? I really dont know

Yeah. I checked ALL FUSES. checked the MAF wires as far as i could get without tearing totally into it. but thats what my next move is. i guess that what ill do.

you have headers? one guy the o2 wires were melted to the rear header and cause the same codes. but i think he was also blowing the fuse.

if you have a open cone filter and the pcm just laying there, check the pcm wires too.

I do have cone air intake but its ram air cold box(i think zzp kit), with separate box for PCM. but i will be checking on that also. should i just giggle wires or what. push them back in?

when the pcm is left laying the wires to it rub the ac lines and wear through sometimes.

what ports is MAF/O2 senor? any links will help

no idea, you just need to look for wires that are rubbed through the factory loom or tape.

the metal loop that holds the harness to the d/s dog bone mount on the engine is another wire rub spot.

code p0742 and p0741 and car wouldnt shift unless i put in park and totally shut off and turn back on. it started on highway. PCM wires??

i pulled the air box out and the pcm and pulled out the wires and checked to see if anything noticeable was going on. i didnt see anything.

Torque converter clutch (TCC) solenoid maybe?

Seems to have my car down to a T


Going to change TCC. What else in the trans should i change while im at that point?
I do plain on new wheel bearing and maybe cv axle. still trying to figure out what one is bad!!

OK friends. let the repair project begin. Have picked up the four senors in the 4t65e hd trans. also new filter and gasket and a shift kit. also going to change the wheel hub. maybe the cv axle. will wait to check that out first before i order that. Will post pics along the way. let hope everything goes well!

Gotta love working on the car whens its 15 out. Had to make something to cover and try to keep warm. More pics to come

Back to the code game. P0756 Shift Solenoid B Performance or Stock Off

Any advise... besides swap trans. not a option at this point.

Just replaced all solenoids last week. the harness to plug in and unplug was real hard. i hope its something that easy and fast to fix!
