Description

Ignition Coil Output Stage 3 Short To Ground is the generic description for Audi code P1345, but the manufacturer may have a different description for your specific vehicle model and year. Currently, we have no further information about the Audi P1345 OBDII code.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine light on (or service engine soon warning light)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

• Faulty spark plug
• Faulty ignition coil
• Intake vacuum leak
• Faulty camshaft position sensor
• Ignition coil harness is open or shorted
• Poor electrical connection in ignition coil circuit

Description

Under CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and severity of the misfire event, and whether it is an emissions problem or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.
The misfire/engine roughness calculation is derived from differences in the period duration (T) of individual gear segments. Each segment period consists of an angular range of 120° crankshaft angle starting 78° before Top Dead Center (TDC).
If the expected period duration exceeds the allowed value, a misfire fault for the affected cylinder is stored in the ECM fault memory. Depending on the measured misfire level, the control unit will illuminate the Service Engine Soon light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether misfires are emissions-related or damaging to the catalyst.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine Light On (or Service Engine Soon Warning Light)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

• Engine mechanical condition – Valve timing disabled
• The camshaft sensor or crankshaft sensor are loose on their mount
• Faulty camshaft position sensor
• Faulty crankshaft position sensor

Technical Notes

If this DTC started after recent internal engine repairs, check the engine mechanical timing. Once the camshaft cover is removed and cylinder #1 is at top dead center, ensure the darkened chain links are aligned with the alignment marks on the exhaust and intake cam gears.

If a P0016 or P1345 is reset without any engine performance issues but the above information has not isolated the cause of the DTC, replace the Cam Phaser actuator gear

Description

The crankshaft position sensor (CKP) is a permanent magnet generator, called a variable reluctance sensor. The sensor’s magnetic field is modified by a reluctance wheel mounted on the crankshaft which has seven machined slots, 6 of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60-degree slots. The CKP sensor produces seven pulses for each crankshaft revolution. The pulse from the 10-degree slot is known as the synchronization pulse. The synchronization pulse is used to synchronize the ignition coil firing sequence with crankshaft position. The CKP sensor is connected to the Powertrain Control Module (PCM) by a signal circuit and a low reference circuit.The camshaft position sensor (CMP) is triggered by a notched reluctance wheel integrated into the exhaust camshaft gear. The CMP sensor provides 6 signal pulses per camshaft revolution. Each notch or feature of the reluctance wheel is of a different size for identification of each cylinder. This means the CMP and crankshaft position (CKP) signals are pulse width coded to allow the Powertrain Control Module (PCM) to continuously monitor their relationship. This relationship is used to determine the camshaft actuator position and control its phasing to the correct value. The PCM also uses this signal to identify the compression stroke of each cylinder and for sequential fuel injection. The CMP sensor is connected to the PCM by a signal circuit and a 12-volt low reference circuit.

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

How to Fix

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine light on (or service engine soon warning light)
• Lack/loss of power
• Engine stalling

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

• Faulty Variable Valve Timing (VVT) sensor
• Variable Valve Timing (VVT) sensor harness is open or short-circuited
• Poor electrical connection in the Variable Valve Timing (VVT) sensor circuit
• Engine Control Module (ECM)

Description

The Variable Valve Timing (VVT) sensor (VVT signal) consists of a signal plate and a detection coil. The VVT signal plate has 1 tooth on its outer circumference and is mounted on the intake camshafts. When the camshafts rotate, the protrusion of the signal plate and the air gap of the detection coil change, causing fluctuations in the magnetic field and generating an electromotive force in the detection coil. The actual camshaft angle is detected by the VVT sensor and it provides feedback to the Engine Control Module (ECM) to control the intake valve timing in response to the condition.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Detected

No signal from the Variable Valve Timing (VVT) sensor to the Engine Control Module (ECM) during startup for 4 seconds or more.

Possible Symptoms
