My truck just started throwing these codes last weekend. They have never thrown these codes befor. Did some reading this morning and I think I can fix some of them but some of the posts say to delete the codes having anything to do with the exhaust system.
Anyways here are the codes..........
P0106 MAP system Performance
P0121 TP Sensor Circuit Insufficient
P0153 HO25 Slow Responce bank 2 sensor 1
P0155 HO25 Heater Performance bank 2 sensor 1
P0172 Fuel trim system rich bank 1
P0175 fuel trim system rich bank 2
U1096 Loss of communication w/IPC

I think I have a bad O2 sensor and a couple of these codes will be fixed. I'm confused about the MAP sensor code because with the research(like said above) some say the sensor may be bad and if not, do some tuning or clean it...........Whats ya'lls opinion.
Please take in account for the cam on the MAP sensor code for lack vacuum @ idle or low RPM's.

Thanks,
James

 

It means your truck is slow

















But i have a spare map sensor you can have when i come up to austin tuesday

 

Your coming up this tues???? Oh, found my phone........happy belated 4th!!!!!!

James

 

looks like you have a bad o2 sensor causing most of it. you can get the map and tp sensor codes if it stalls.

 

It does stall some.......I was thinking it was with tuning. But I'll R&R the TP sensor too.

James

 

So the MAP could be causing the fuel trim rich bank 1&2 and a bad O2 causing the heater/slow responce bank 2??? I might be way off on this.......

James

 

Are you using a code reader or scan tool. With a scan tool you can watch these PIDs in real time.

 

no. the o2 could be causing the heater/slow response and rich conditions and the map code is caused from the stalling.

 

looks like to me you need a pass side, front O2 sensor. Clear the rest of the codes.... I had to tune my p0106 code out, tried a map sensor, didnt fix a thing...

 

I have HPT......
