ok i got a code p1153 lean on bank 2, well i think i solved the prob but want to seee if this is so. how many times must i start the car and how long must it run til it clears if it is going to do so? thanks. like 3 starts @ running for 45 sec for example

 

P1153 insufficient switching - supposed to turn off the MIL after 3 consecutive warm up cycles test runs and doesn't fail, stays as a "history" code for 40 cycles w/o a failure. I'd just clear the code if you can, or reset the PCM. If the problem is still there the SES will return on the second consecutive warm up cycle the diag runs and fails.

 

ok thanks how long should i run it each time. i don't want to run too long cause that side is running lean is what the code says.

 

I'd just reset the PCM, will clear all codes, along with any in history. Idle will be a little grumpy at first until it relearns.

Turn key on, don't start car
Pull PCM BATT and PCM IGN fuses in engine compartment
Wait 5-10 min
Turn ignition off
Replace fuses

 

ok thanks i will try that

 

ok i just did it. if it fails will the code come back instantly or on the second start, third start etc just wondering thanks

 

Sounds like you got the PCM reset - P1153 illuminates the SES on the second ignition cycle with a failure. You can also try a couple drive cycles- www.obdii.com/drivecycle.html

 

awesome i will do that drive cycle in the morning thanks for a great link. it will go in my favorites

 

Can you pass OBDII emissions test (scan) after doing this? Or will it not be "ready"?

 

No, you'll need some OBDII drive cycles because the readiness tests will be reset and have to start over.

 

I'm stock, and have the P0420 "cat" code. I'll try going through the dealer for the federal warranty. O2 Sims would cure that code, right? I don't have to go for emissions until August.

 

02 sims will turn the light off - but if the cat is coming apart inside/rattling/clogged/rear 02 is bad, etc. you'll still have the problem.
