hey guys, ive been looking into this problem for a while now and i found a few good leads. my 8 revs from 1-7K no problem but stops at 7 and sounds like its being cut off. i have the CEL P0410. after looking up a few threads i found a couple options of what it might be.

1. clogged Cat, so i took it out and put my midpipe back in.
2. the SSV was dirty and not operating correctly, so i took it out and cleaned it and the houseing. ( i did that today )

the others were mentioned to not affect drive-ability like the Air pump going bad and such like that.

my next place to go is the solenoid. but id like some input. im drained and running outa options. the lack of 8000 RPM is deadly, lol. any help would be awesome.

Flashing CEL??

if it were your ssv you'd likely have problems well before 7k. I'll take a WAG and say ignition

2 second search found me this

A code P0410 may mean that one or more of the following has happened: Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump Blown AIR pump fuse due to freezing up

hey guys, i did flash the CEL, i have an access port.
and i hadnt thought about ignition. ill check that out next.

the only problem is i dont see the Air pump stopping my engine from reving past 7k. only thing it does is preheat the cat. which i do not have anymore.

thanks yall for the help and input.

logalinipoo

Flashing cel is always a missfire. Check that out and also drop your midpipe and look to make sure the cat is a nice grid and not melted or clogged. The 410 code it cat related even though its the air pump just check it. Its a task of jacking up your car and pulling 3 bolts.

update* i took out the spark plugs and cleaned them, but that didnt fix the problem. im slowly running out of options lol. the little **** on the back side (toward the inside of the car) are those the air actuators? i started to turn them by hand hoping to free them up by hand but i wasnt sure if i was doing anything or not so i stopped.

200.mph

when was the last time you replaced coils wires and plugs? if you cel is flashing change all of these

lawlorjuice

iTrader: (2)

idk, prolly 6 months ago roughly. beginning of the year. but the CEL isnt falsh anymore. i reset the ECU, its normal not. no CEL anymore. ive been driving it for a little while. about 40 minutes a day or so for about 5 days.

do you think the MAF sensor would have anything to do with it? i did take it out and clean. nothing happened.

lawlorjuice

iTrader: (2)

I'm completely lost I need help! I checked plugs, coils, SSV, reflash CEL. I simply can't think of anything else. I'll be taking the throttle body to clean as my next option.

the only way it would be a TB is if it isn't opening fully or *if the internal electronics are bad* (could be a possibility), cleaning it is fluffer work

would at least check the leading side, this also applies to OE coils

maybe low fuel pressure/bad pump

could be any number of things, you have no data, troubleshooting is mostly a process of analysis and elimination

or it could be the PCM

DTC P0410

BHE010200400W01

DTC P0410



AIR system problem

DETECTION CONDITION

• The PCM monitors the front HO2S output current when the AIR control is operating. If the output current is more than the specification, the PCM determines that there is an AIR system problem.

Diagnostic support note
• This is an intermittent monitor (AIR system).
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• AIR system malfunction
• PCM malfunction

thank you, teamrx8. ill be looking into this over the next couple of days and give an update next week sometime.

lawlorjuice

just to verify, the FREEZE FRAME DATA, is something i need a specific tool to get, or can use my accesstuner to get it.

lawlorjuice

so i did a compression test today, and i got: 95, 95 and 90, 90. how low can it go before my engine goes?

logalinipoo

Umm are you missing some?

lawlorjuice

iTrader: (2)

idk it was my buddies test, thats what he said. so im not 100% sure what he means by it but he said it should be 120. idk anyone know if this is accurate

logalinipoo

It depends on a lot of things. 120 is a real strong engine.

With my rebuild i was able to get 70 just spinning the engine over by hand on my living room floor. It is supposed to be tested at 250 rpm and not with a standard tester.

ok, good to know. i had a feeling considering my buddy does paint work but has been filling in as a helper for a mechanic, he doesnt exactly know what he is doing. i ordered new spark plug wires from BHR. and got new spark plugs. the coils are good. im gonna try to get it into a shop to test compression soon.

AAaF

One thing, you could check your VDI is working. This opens at 7250RPM.

lawlorjuice

iTrader: (2)

thats part of the stock air intake correct? if it is would it still apply if i had AEM intake installed? ill look into it.

thanks

lawlorjuice

iTrader: (2)

as i was lol. thanks AAaF, found a video on youtube where they test it. ill look deeper and test this shortly. on a good note my spark plug wires came in so thats awesome thanks to BHR to putting up with my stupidity lol.

lawlorjuice

iTrader: (2)

does anyone know if a failed VDI actuator would throw a code? im not getting anything besides p0410.

lawlorjuice

UPDATE**

so i replaced my wires and plugs.

at the same time i was looking over the VDI and connections on the back on the manifold. after i disconnected them i found something that looked like oil (dark and wet) on the inside of the connection pieces i cleaned them off best i could. any idea of how that could have happened? over the next few days im going to be doing extensive cleaning to get all nastiness out so i might be able to pin point a leak.

thanks everyone for the help.
