Code P1D67 Fiat Description
The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event, the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The VVA Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting the lift and duration of the valve opening.
The Diagnostic Trouble Code (DTC) will be set when the PCM detects a short circuit condition between the VVA Solenoid Control return circuit and the VVA Solenoid Control signal circuit.
What are the Possible Causes of the DTC P1D67 Fiat?
- Faulty Variable Valve Actuator (VVA) Solenoid
- Variable Valve Actuator Solenoid harness is open or shorted
- Variable Valve Actuator Solenoid circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)

Frequently Asked Questions about P1D67 Fiat Code
1. What does the OBDII code P1D67 mean on a Fiat?
The P1D67 code indicates an issue with the Cylinder 3 Oil Supply Solenoid Valve Performance, suggesting it may not be functioning properly.
2. What are the symptoms of the P1D67 code in a Fiat?
Common symptoms include engine misfires, reduced performance, rough idling, or an illuminated check engine light.
3. What causes the P1D67 code to appear?
The most common causes are a faulty oil supply solenoid valve, low or dirty engine oil, electrical issues like damaged wiring or connectors, or in rare cases, an engine control module (ECM) fault.
4. Can I drive my Fiat with the P1D67 code active?
While it may be possible to drive, doing so can cause further engine damage. It’s best to address the issue promptly to avoid costly repairs.
5. How can I fix the P1D67 code on my Fiat?
Start by checking the engine oil level and quality, inspect the wiring and connectors for damage, and replace the Cylinder 3 oil supply solenoid valve if necessary.
6. How much does it cost to repair the P1D67 code?
Repair costs vary but typically range from $150 to $400 for parts and labor, depending on whether the solenoid valve or wiring requires replacement.
7. Can dirty oil cause the P1D67 code?
Yes, dirty or low engine oil can restrict the solenoid valve’s operation, leading to performance issues and triggering this code.
8. How do I diagnose a P1D67 code?
Use an OBDII scanner to confirm the code, then check engine oil, inspect the solenoid valve, and test the electrical connections for continuity and damage.
9. Is the P1D67 code specific to Fiat vehicles?
Yes, the P1D67 code is a manufacturer-specific code for Fiat models and relates to the Cylinder 3 oil supply solenoid valve.
10. Can a faulty ECM cause the P1D67 code?
While rare, a malfunctioning engine control module (ECM) could potentially cause this code, but it’s more likely to be an issue with the solenoid valve or wiring.
