F00316: Renault Dtc
The Renault diagnostic fault code (sometimes seen as DTC F003_16) typically indicates a Computer Power Supply issue where the Feed Voltage is Too Low Code Details Module(s): Most commonly associated with the ABS (Anti-lock Braking System) Instrument Cluster Description:
If the alternator's voltage regulator is failing, it may provide insufficient "feed voltage" to the UCH or IC. Parasitic Draw: renault dtc f00316
Frequently Asked Questions
Can I drive with DTC F00316?
Yes, for short distances. However, the ECU may eventually block DPF regeneration, leading to a clogged DPF, which is far more expensive to fix (upwards of $2,000). Do not ignore it for more than a few weeks. The Renault diagnostic fault code (sometimes seen as
Is your car currently struggling to start, or are you just seeing the code in a diagnostic menu? BRAKING FAULT Renault Error [SOLVED] Depleted Car Battery Location: Mounted in the exhaust pipe, downstream of
The Role of the Particulate Sensor (Renault Part No. typically 22790-00X or 20874-000XR)
- Location: Mounted in the exhaust pipe, downstream of the DPF.
- Technology: Uses two electrodes with a voltage applied across them. Soot particles accumulating on the sensor change its resistance or capacitance, which the ECU interprets as a soot concentration.
- Communication: Sends a voltage signal back to the ECU (usually between 0V and 5V). A high voltage indicates high soot accumulation; a low voltage indicates clean exhaust.
4. ECU Software Glitch (3% of cases)
Early firmware on Renault EMS3130 ECUs had a bug where it falsely flagged F00316 during rapid ignition cycling (e.g., stalling and restarting quickly). A dealer reflash solves this.
- Illuminated Check Engine Light (SERV or OBD light): The most common symptom.
- Reduced Engine Power (Limp Mode): If the ECU cannot monitor DPF efficiency, it may limit performance to protect the engine.
- Blocked DPF Regeneration: The ECU relies on the PM sensor to start regeneration cycles. With a faulty voltage signal, it may refuse to regenerate, leading to a clogged DPF over time.
- Forced Regeneration Failure: A diagnostic tool may attempt to run a forced DPF regen, but the process will abort if it sees an implausible voltage from the PM sensor.
- No noticeable change in fuel economy or performance (in early stages).
5. Diagnostic Procedure
Step 1 – Visual Inspection
- Check connector at injector 3 for corrosion, damage, or loose pins.
- Inspect wiring harness from injector 3 back to ECU for chafing, burns, or pinches.
- Verify ECU connectors are clean and dry.
