P1145 – Intake Valve Distribution Control Performance, Bank 2

P1145 Possible Causes

  • Faulty intake valve timing control solenoid valve
  • Intake valve timing control solenoid valve wiring harness is open or shorted
  • Poor electrical connection in the intake valve timing control solenoid valve circuit
  • Faulty crankshaft position sensor
  • Faulty camshaft position sensor

How to Fix Code P1145?

Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

When is the Code Detected?

When there is a discrepancy between the target angle and the phase control angle degree, the valve will stop functioning and the ECM will trigger code P1145.

Possible Symptoms

  • Engine light on (or engine service warning light soon)
  • Possible engine lack/loss of power
  • Possible rough engine idle

P1145 Meaning

This mechanism hydraulically controls the cam phases continuously with the fixed operating angle of the intake valve.
The engine control module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve based on the driving condition. This controls the intake valve closing/opening timing to increase engine torque in the low/mid speed range and output in the high speed range.
The intake valve timing control solenoid valve changes the oil amount and flow direction through the intake valve timing control unit or stops the oil flow. The longer pulse width advances the valve angle. The shorter pulse width retards the valve angle. When the ON and OFF pulse widths become equal, the solenoid valve stops the oil pressure flow to fix the intake valve angle at the control position.

P1145 2001 NISSAN PATHFINDER – Intake Valve Timing Control Performance, Bank 2

P1145 2001 NISSAN PATHFINDER Possible Causes

  • Faulty intake valve timing control solenoid valve
  • Intake valve timing control solenoid valve harness is open or shorted
  • Poor electrical connection in intake valve timing control solenoid valve circuit
  • Faulty crankshaft position sensor
  • Faulty camshaft position sensor

How to Fix Code P1145 2001 NISSAN PATHFINDER?

Start by checking the “possible causes” listed above. Visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Technical Notes

Since the intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stick open or closed. Before replacing the valve, change the engine oil and filter and reset the engine code.

When is the Code Detected?

When there is a discrepancy between the target angle and the phase control angle degree, the valve will stop functioning and the ECM will trigger the P1145 code.

Possible Symptoms

  • Engine light on (or service engine soon warning light)
  • Possible engine power loss/lack of power
  • Possible rough engine idle

Denmark’s Tax Shift Sparks French EV Market Opportunity

How Denmark’s Fiscal Decision Benefits French Electric Vehicles

PowerGo DC HPC charging station in Denmark

Denmark’s recent decision to postpone electric vehicle registration tax increases creates unexpected advantages for France’s automotive sector. This one-year deferral provides crucial breathing room for European EV manufacturers and infrastructure developers.

Market Stability and Supply Chain Benefits

The Danish postponement stabilizes near-term EV demand in Scandinavia, allowing French automakers to maintain production schedules without sudden market disruptions. This continuity benefits French companies like Renault and Stellantis, who can now plan export strategies with greater certainty. The decision comes at a critical time when European automakers face supply chain challenges and fluctuating consumer demand patterns.

Infrastructure Development Opportunities

French charging infrastructure companies gain valuable time to establish partnerships and expand operations in Denmark. Companies specializing in fast-charging technology can use this period to demonstrate their capabilities in the Danish market, potentially creating reference projects that strengthen their position across Europe. The delayed tax implementation allows for more gradual market penetration strategies.

Technology Transfer Potential

French EV technology firms can leverage this window to showcase innovations in battery efficiency and charging solutions. Denmark’s progressive approach to renewable energy integration provides an ideal testing ground for French technologies destined for broader European deployment. This alignment between French innovation and Danish energy infrastructure creates synergistic opportunities for both markets.

The Danish tax decision represents more than just temporary relief—it establishes a framework for strategic cooperation between French and Scandinavian EV ecosystems. This intermarket coordination could accelerate the broader European transition to electric mobility while strengthening France’s position in the continental EV value chain.

P1145 AUDI – Short to Positive Mass Air Flow Sensor

Code P1145 AUDI: Mass Air Flow (MAF) Sensor Problem

What does code P1145 mean on an Audi?

Code P1145 is related to a problem with the Mass Air Flow (MAF) sensor. This sensor measures the amount of air entering the engine to allow the ECU to adjust the air/fuel mixture.

This code indicates that the MAF sensor signal is shorted to positive, which can lead to engine malfunction.

Possible symptoms of code P1145

🔸 Check Engine light on
🔸 Unstable idle or engine stalling
🔸 Lack of power, difficult acceleration
🔸 Excessive fuel consumption
🔸 High pollutant emissions

Possible causes of code P1145

✅ Faulty or dirty MAF sensor
✅ Damaged MAF sensor wiring (cut, melted, or short-circuited)
✅ Corroded or poorly connected connectors
✅ Clogged air filter restricting airflow
✅ Air leak in the intake circuit (cracked or poorly secured hoses)

How to diagnose and repair code P1145 on an Audi?

1. Visually inspect the MAF sensor and its wiring

🔎 Inspect the Mass Air Flow sensor and its connector
✅ Look for bent pins, cut wires, or corrosion.
✅ If wires are damaged, repair or replace them.

2. Clean the MAF sensor

💨 Remove the MAF sensor and clean it with a dedicated MAF cleaner.
⚠️ Never use brake cleaner or gasoline, as this could damage it!
✅ Let it dry completely before reinstalling.

3. Check the electrical connections

📌 Unplug the MAF connector and check the pins using a multimeter.
🔧 Measure the sensor’s supply voltage (~5V typically).
✅ If no voltage is present, check the wiring harness back to the ECU.

4. Check for air leaks in the intake

🔎 Check that the intake hoses are not cracked or poorly secured.
✅ If a leak is detected, replace or tighten the hoses.

5. Replace the MAF sensor if necessary

🛠️ If the sensor is too dirty or damaged, replace it with an OEM or equivalent quality MAF sensor.
⚠️ Avoid low-quality sensors that can cause other problems.

Common repairs for code P1145

🔧 Cleaning the MAF sensor
🔧 Repairing or replacing the sensor wiring harness
🔧 Replacing the MAF sensor (if necessary)
🔧 Checking and replacing the air filter (if dirty)
🔧 Repairing air leaks in the intake circuit

Common mistakes when diagnosing code P1145

❌ Replacing the MAF sensor directly without testing its wiring and connections
❌ Ignoring air leaks in the intake that distort the MAF measurement
❌ Using an unsuitable cleaner that damages the sensor
❌ Neglecting the condition of the air filter which can restrict airflow

Conclusion

Code P1145 indicates a problem with the MAF (Mass Air Flow) sensor, often caused by an electrical short circuit, a dirty sensor, or an air leak in the intake.

➡️ Start by inspecting and cleaning the sensor.
➡️ Check the electrical connections and the sensor wiring harness.
➡️ Look for possible air leaks or a dirty air filter.
➡️ If the sensor is faulty, replace it.
