Obd codes

I just got a 06 6cyl 2wd base tacoma an wanted some ideas on where to start with the codes .
I use my elm to get them an know some on obd2 an sensors.
P0102. MAF
P0113 air intake. IAT
P0441. Emissions. /Purge
P0455 emmisions gross leak
P2433..secondary air injection system bank 1

2 same pending
P0455
P0441


I just got a new new gas cap to rule that out ..an did a elm32 run test an did not see a reading on maf sensor. .it was 0..there may be a leak after muffler also.
Whats with the p02433?
What all should i look at .? I know 1 code can lead to another after not looked at..
Ill start w looking for leaks an maf too.
Thanks

 

With the key ON, unplug the MAF sensor and see if you have 12v on pin #1 (Blue/White) wire.

 

Ok an with it off is there a ohms test or way to test sensor?

 

Not really.
Most of the time you go off scan tool data.

FSM has you do circuit checks and then throw a MAF at it.

 

Thanks! Ill test those ..What about the other codes ? AIR INTAKE AN AIR INJECTION .,ETC

An is there a link or download for fsm anywhere?

 

You need to address the p0102 first.
But I can get you some info on the other codes.

 

It is showing 11.8 at the positive..an ground is good.
I cleared codes an
I reconnected it all an started it up an it read 1lb on maf reading on ELM .
Is that correct ?..

 

I rechecked it an its at 0 lb per min ..went to 1 as giving gas ..? Is this normal

is the air pump supposed to be on?

Where is the purge valve ,an is 6.7 then 11.0 then 12.2 on commanded evap purge readings mean its working?

Absolute evap system vapor 0 in h20.

 

Since you have a P2433 code I have to assume you have a 2.7L 4cyl and not the 4.0L V6 as the 4.0L does not have the Secondary Air Injection System until 2012.

Do these codes reset immediately when cleared?

Can you set your scan tool to display grams per second (g/s)? Pounds per minute (Lb/Min) isn't really useful for checking what the MAF is reading.

The Secondary Air Injection System pump will only run on a cold start for 30-60 secs, after that it's not used.

Not sure what you mean here?

It should read 0 except when the engine is running and the purge valve is open or when the engine is off and the system is running an EVAP test.

 

Umm wrong thread?

 

Yeah……
How I did that?
I don’t know?
