I threw a P1519 which I don't know what it is

and a

P325

I have no idea what they mean, I think she said knock sensor but i dont' know. Please help out.

 

P0325 Knock sensor circuit malfunction

P1519 Idle Air Control Valve circuit malfunction

 

are these things pretty big things?

 

Notes

DTC P1519: IAC Valve Circuit Malfunction

Reset the ECM.
Turn the ignition switch ON (II). Is DTC P1519 indicated? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the IAC valve and at the ECM.
Turn the ignition switch OFF.
Disconnect the IAC valve 3P connector.
Turn the ignition switch ON (II).

Measure voltage between IAC valve 3P connector terminal No.2 and body ground. Is there battery voltage? YES - Go to step 7. NO - Repair open in the wire between the IAC valve and the PGM-FI main relay.
Turn the ignition switch OFF.


Check for continuity between body ground and IAC valve 3P connector terminal No.1. Is there continuity? YES - Go to step 9. NO - Repair open in the wire between the IAC valve and G101.
Disconnect ECM connector B (25P).


Check for continuity between body ground and ECM connector terminal B23. Is there continuity? YES - Repair short in the wire between the IAC valve and the ECM (B23). NO - Go to step 11.

Connect IAC valve 3P connector terminals No.1 and No.3 with a jumper wire.


Check for continuity between ECM connector terminal B23 and body ground. Is there continuity? YES - Go to step 13. NO - Repair open in the wire between the IAC valve and the ECM (B23).
Remove the jumper wire from the IAC valve 3P connector, then reconnect the IAC valve 3P connector.
Turn the ignition switch ON (II).


Measure voltage between body ground and ECM connector terminal B23. Is there battery voltage? YES - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM. NO - Replace the IAC valve.

 

DTC P0325: Knock Sensor Circuit Malfunction



Reset the ECM.
Start the engine. Hold the engine at 3,000 rpm with no load (in neutral) until the radiator fan comes on, then let it idle.
Hold the engine at 3,000 - 4,000 rpm for 10 seconds . Is DTC P0325 indicated? YES - Go to step 4. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the knock sensor and at the ECM.
Turn the ignition switch OFF.
From underneath the vehicle, reach above the front of the starter motor, and disconnect the knock sensor 1P connector.


Disconnect ECM connector C (31P), then check for continuity between ECM connector terminals C22 and body ground. Is there continuity? YES - Repair short in the wire between ECM (C22) and the knock sensor. NO - Go to step 7.


Connect knock sensor connector terminal No.1 to body ground with a jumper wire.


Check for continuity between ECM connector terminal C22 and body ground. Is there continuity ? YES - Go to step 9. NO - Repair open in the wire between the ECM (C22) and the knock sensor.
Substitute a known-good knock sensor and recheck. Is DTC P0325 indicated? YES - Substitute a known-good ECM and recheck. If symptom/indication goes away replace the original ECM. NO - Replace the original knock sensor.

 

holy crap man, thanks!
