P2067 — Fuel Level Sensor "B" Circuit Low

Will P2067 clear itself?

Sometimes P2067 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What is the most common cause of P2067?

The most common causes are: weak fuel pump or clogged fuel filter, faulty fuel rail pressure sensor or wiring, faulty fuel pressure regulator.

How do I diagnose P2067 myself?

Start with a scan: confirm P2067, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the fuel level sensor "B", and verify the suspect component against live data before buying parts.

How much does it cost to fix P2067?

Replace the pressure regulator or sensor — $150–$450; Replace the fuel pump — $400–$900; Replace the fuel filter — $80–$200; Clean or replace injectors — $200–$800. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P2067 mean?

P2067 — Fuel Level Sensor "B" Circuit Low. A fault in the fuel delivery and mixture control. Short, gentle driving to a shop is usually possible. Typical causes: weak fuel pump or clogged fuel filter, faulty fuel rail pressure sensor or wiring, faulty fuel pressure regulator.

What does P2067 mean?

P2067 is logged by the onboard diagnostics when the fuel delivery and mixture control does not behave as expected. The official definition is “Fuel Level Sensor "B" Circuit Low”. This is a powertrain (engine/transmission) category code.

“Circuit low” means the voltage on the fuel level sensor "B" circuit stays below the expected minimum — close to ground. The usual physical reasons are a short to ground, a chafed wire touching metal, a missing supply voltage, or a failed component dragging the signal down.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2067 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of P2067

• increased fuel consumption
• loss of power under load
• fuel smell in severe cases
• hard starting or long cranking
• rough idle and hesitation
• Check Engine Light on

What causes P2067?

• signal wire shorted to ground (chafed insulation)
• missing supply voltage to the fuel level sensor "B"
• failed fuel level sensor "B" pulling the signal low
• clogged or leaking fuel injectors
• faulty fuel pressure regulator
• weak fuel pump or clogged fuel filter
• vacuum or intake leaks skewing the mixture
• contaminated or incorrect fuel

How to diagnose P2067

1. Connect an OBD2 scanner, confirm P2067 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
2. Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
3. Visually inspect the wiring harness and connectors related to the fuel delivery and mixture control for damage, corrosion, chafing or poor contact.
4. Check for supply voltage at the fuel level sensor "B" connector first; then measure resistance from the signal wire to ground — near-zero ohms confirms a short to ground in the harness.
5. Measure fuel pressure at the rail and compare with factory specification at idle and under load.
6. Check short-term and long-term fuel trims in live data to see which way the mixture is off.
7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2067 does not return.

How to fix P2067

Start with the cheapest and most common causes before replacing expensive parts:

• Replace the pressure regulator or sensor — $150–$450
• Replace the fuel pump — $400–$900
• Replace the fuel filter — $80–$200
• Clean or replace injectors — $200–$800

How much does it cost to fix P2067?

Repair cost depends on which component actually failed. Typical scenarios for P2067 (parts and labor, USD, independent shop rates):

• Replace the pressure regulator or sensor: $150–$450
• Replace the fuel pump: $400–$900
• Replace the fuel filter: $80–$200
• Clean or replace injectors: $200–$800

Overall, fixing P2067 usually costs between $80 and $900. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Can you drive with P2067?

Drive with caution. Mixture and fuel-pressure faults can cause stalling, hesitation in traffic and — when severe — catalyst damage. Avoid long trips until diagnosed.
