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.

  1. Illuminated Check Engine Light (SERV or OBD light): The most common symptom.
  2. Reduced Engine Power (Limp Mode): If the ECU cannot monitor DPF efficiency, it may limit performance to protect the engine.
  3. 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.
  4. 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.
  5. 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.
  • 1.5 dCI (K9K): 166305283R, 166305284R, 8200878652
  • 1.6 dCI (R9M): 166307457R
