Error Code P0351 for a 2005 Toyota Avalon


Possible causes
Faulty Ignition Coil 1
Ignition Coil 1 harness is open or shorted
Ignition Coil 1 circuit poor electrical connection
Faulty Engine Control Module (ECM)

What does this mean? When is the code detected? Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/Loss of Power Engine may be harder to start Engine hesitation Rough engine idle P0351 TOYOTA Description: The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.

Chevy code P1682?


P1682 Chevrolet - Ignition 1 Switch Circuit 2

Possible causes
- Faulty ignition switch
- Ignition Switch harness is open or shorted
- Ignition Switch circuit poor electrical connection
- Faulty Engine Control Module (ECM)
What does this mean? What does this mean?
When is the code detected?
The ECM has detected a voltage deifference between two circuits
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible no crank or start
P1682 Chevrolet Description

There are 2 ignition 1 voltage circuits supplied to the Engine Control Module (ECM). The first ignition circuit is provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1 voltage circuit is supplied by the run/crank relay through a fuse, and is used to power the remaining internal ECM circuits. If the ECM detects a voltage difference between the 2 ignition 1 voltage circuits, DTC P1682 will set

Engine Code PO430


P0430 Ford - Catalyst System Efficiency Below Threshold Bank 2

Possible causes - Three way catalyst converter Bank 2
- Exhaust tube
- Intake air leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing
- Engine Control Module (ECM) Tech notes As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first.

P0350 Hyundai Description
The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Codes p0351 miss and is goverened at 2800 rpms.


P0351 is Ignition Coil A Primary/Secondary Circuit Malfunction.
Possible causes: - Open or short in the ignition coil circuit - Ignition coil circuit shorted to ground - Ignition coil connector - Damaged ignition coil - Damaged PCM or
Possible solution - If damage, repair ignition coil circuit - Replaced ignition coil - Replaced PCM or ECM When is the code detected? The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.
P0351 Description: The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.
Hope this helps :)

P0352 code came up what might be the problem


P0352 - Ignition Coil B Primary/Secondary Circuit Malfunction
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

When is the code detected?
The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation

Possible causes
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or

Possible solution
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM


Hope helps with this (remember to rate this answer).

On my 1998 crysler sebring I am getting OBD II codes of 40 and 41,Transmission & engine module,any suggestions where to start? Thanks.


code 40-
Possible causes - 1/1 And 2/1 O2 sensors harness circuit shorted
- 1/1 And 2/1 O2 sensors harness circuit connectors (wrong connection)
- Faulty Powertrain Control Module (PCM) P0040 CHRYSLER Description At ignition on the Powertrain Control Module (PCM) checks the voltage on the ground side of the O2 sensor harness connector. If voltage is higher than two volts the P0040 code will set. code 41- Possible causes - 1/2 And 2/2 O2 sensors harness circuit shorted
- 1/2 And 2/2 O2 sensors harness circuit connectors (wrong connection)
- Faulty Powertrain Control Module (PCM) P0041 CHRYSLER Description At ignition on the Powertrain Control Module (PCM) checks the voltage on the ground side of the O2 sensor harness connector. If voltage is higher than two volts the P0041 code will set.
