Check engine light PLease help

[X2cb7s]

Hey im getting a check engin light, how do i check??? I have a H22 and all the sudden now it falls on its face. it will idle like a champ but as soon as i give it gas it stumbles and burps.

i just got a check engine but dont know how to check.

I found the blue plug under kick panel is that it?????

Also what could possibly make it do this?

I have not driven the car in 8 months and all the sudden its doing this?

[ExplodingCake]

stick a paperclip in the connector and read the flashes

a long blink = 10
a short blink = 1
It will repeat after all the codes are done.

Compare to this list to see what the problem is:

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Fuel Tank Pressure Sensor low input
92 Evaporative Emission Control System insufficient purge flow

Yes its the blue plug under the dash on the passengers side, but not to use if you can still check the light since you have the H22.

[X2cb7s]

Check engine

what do you think it could be? i mean it was fine and sitting for 8 months then all the sudden it does this.

pull the code , your answer is there.

[X2cb7s]

so with the h22 the Plug is no longer any good?

[ExplodingCake]

you can try.

[X2cb7s]

ok and if i cant pull codes from the plug? then where do i get them?

[X2cb7s]

ok i pulled the code, this sucks! it was 23, knock. But i still dont see how it went out while parked for 8 months. Is there something els that could cause the 23? like maybe something making the knock mess up?

[ExplodingCake]

Replace the knock sensor then.

well since it sat for 8 months the gas could of went bad and causing it to miss fire causing the stumble and burp throw sum fuel additve in it let run till the gas is almost empty or drain the tank what ever you chosse is easier change the fuel filter and add fresh gas and see how she runs

[X2cb7s]

yah i already changed fuel filter and put seafoam in the tank, also ran right through intake to clean carbon out of intake and injecs.....But still falls on its face....... And its crazy..... Do you think getting water in something on the motor could have this happen??????? The bay got washed out with hi pressure water could it have an effect on anyhting under hood besides cap and wires??

[ExplodingCake]

Never use high pressure on the engine bay.. Shit some of the sensors are prolly fucked.. Like I said try changing the knock sensor.

[drkshdw107]

this sounds more like the TPS sensor...whats happening is the computer is not getting the throttle position reading...but when you step on the throttle, you are opening the throttle plate, causing tons of air to be sucked in, and the computer doesn't know to give the engine more fuel...being that your engine is running lean can cause a knock and set off the knock sensor...I have seen this happen on other cars...but not on mine personally...try changing the TPS sensor...the knock sensor is not a likely sensor to go bad...it usually only sets a code if it detects a knock...which it is. Good luck.

yeah pressure washing can really skrew with things like pullinh vaccum lines out and ripping wires in sensors.... and i would go with everything drkshdw wrote
