P2067 on Jeep: How to Diagnose & Fix
Fuel Level Sensor "B" Circuit Low Input
1 Jeep model · 1 documented issue · $150-$800 repair
On Jeep vehicles, P2067 (fuel level sensor "b" circuit low input) is most often reported on the 2007-2017 Jeep Patriot as 4WD Secondary Fuel Sender Ignored After Instrument Cluster or TIPM Is Configured as a 2WD Vehicle ($150-$800 repair). The diagnostic that saves you the money is done before you touch the fuel tank. Watch the fuel level Sensor 2 / secondary sender PID with a scan tool while the tank has a known amount of fuel in it. Each section below gives the symptoms, how to confirm the cause, the fix, parts and sources for that model.
Common causes of P2067 (all vehicles)
- Short to ground in the signal circuit
- Faulty fuel level sender 'B'
- Corroded or shorted connector
- Damaged wiring harness
- PCM/ECM fault (rare)
P2067 on Jeep by model: symptoms, diagnosis and fix
This is one of the few P2067 cases where the fuel level sender is not the problem at all, and it catches technicians out repeatedly on the Patriot and its Compass twin. Front-wheel-drive Patriots have a simple single-sender fuel tank. Four-wheel-drive Patriots do not: the rear driveshaft and rear differential force a saddle-shaped tank, so 4WD cars get a second fuel level sender in the opposite lobe of the tank, and the instrument cluster is responsible for reading that second sender and reporting the level onward. The cluster and the TIPM (Totally Integrated Power Module) both carry vehicle configuration data that tells them which body they are installed in. If that configuration says 2WD — because a used or remanufactured cluster or TIPM was installed, because a module was flashed with the wrong VIN or the wrong model year, or because the configuration was corrupted — the module simply stops looking for a second sender. The secondary fuel level signal is then never reported, the PCM sees a persistently low Sensor 2 input, and P2067 sets and refuses to clear. A documented professional case involved a 2016 Patriot Latitude 2.4L whose TIPM configuration data identified it as a 2015 2WD model; the fuel sender and its wiring tested fine. The giveaway is that the fuel level code almost never travels alone. Because the same configuration data drives the drivetrain, the same car had a 4WD Lock switch that did nothing even though the transfer case would engage when commanded with a scan tool. The mirror-image version of this fault also exists: fitting a 4x4 cluster into a 2WD Patriot makes the cluster look for a secondary sender that physically is not there. Owners chase this for months, replacing the fuel pump module — sometimes twice — and still have the code, because there was never anything wrong with the part they bought.
Common Symptoms
- Fuel gauge reads empty regardless of how much fuel is in the tank
- P2067 returns immediately after clearing, even with a new fuel pump/sender
- 4WD Lock switch does nothing, though the transfer case engages when commanded by a scan tool
- 4x4 and traction control telltales do not illuminate during the key-on cluster self-test
- Secondary fuel level sender PID reads zero while the sender itself tests good
- Check engine light on
How to Fix
The diagnostic that saves you the money is done before you touch the fuel tank. Watch the fuel level Sensor 2 / secondary sender PID with a scan tool while the tank has a known amount of fuel in it. If Sensor 1 reads a sensible voltage and Sensor 2 reads flat zero regardless of fuel level, and the sender ohms out correctly at the connector on top of the tank, the sender is fine and the fault is upstream in how the vehicle is configured. Then cycle the key on and watch the cluster's self-test sweep and telltale bulb check: if the 4x4 telltales never light, the cluster is not behaving as a 4WD cluster. Confirm the drivetrain half of the symptom too — if the 4WD Lock switch is dead but the transfer case engages when commanded by the scan tool, that is the same configuration mismatch showing up in a second system. The repair is a software one. Using the factory scan tool (wiTECH), read the configuration data stored in the TIPM and the instrument cluster and compare it against the vehicle's actual VIN, model year and drivetrain. In the documented case, restoring the TIPM to its factory default configuration and reprogramming it under the vehicle's own VIN resolved both the P2067 and the 4x4 fault in about fifteen minutes, with no parts replaced. If a used cluster or TIPM was fitted from a 2WD donor, it must be reconfigured to the receiving vehicle rather than simply plugged in — and in some cases a mismatched module cannot be reconfigured and has to be swapped for a correct one. This is dealer or well-equipped independent work because it requires the manufacturer's tool and, in some cases, an online security unlock; budget roughly one to two hours of diagnostic and programming labor. Only after the configuration is confirmed correct and P2067 persists should you go after the hardware — at that point inspect the fuel pump module connector on top of the tank for corroded terminals, then test the secondary sender's resistance sweep directly, and replace the sender or the complete pump module assembly if it is genuinely out of range. Reconfiguration typically runs $150 to $350; a fuel pump/sender module replacement, if it truly is needed, runs about $400 to $800 installed.

What does P2067 mean on a Jeep?
P2067 stands for "Fuel Level Sensor "B" Circuit Low Input." Set when the PCM detects the Fuel Level Sensor 'B' signal voltage is lower than expected, typically indicating a short to ground or a failed sender. On Jeep it is documented across 1 model: Patriot.
How do I diagnose P2067 on a Jeep Patriot?
The diagnostic that saves you the money is done before you touch the fuel tank. Watch the fuel level Sensor 2 / secondary sender PID with a scan tool while the tank has a known amount of fuel in it. If Sensor 1 reads a sensible voltage and Sensor 2 reads flat zero regardless of fuel level, and the sender ohms out correctly at the connector on top of the tank, the sender is fine and the fault is upstream in how the vehicle is configured. Published repair guidance and available estimates are in the Patriot section on this page.
What causes P2067 on Jeep vehicles?
Documented causes on Jeep: 4WD Secondary Fuel Sender Ignored After Instrument Cluster or TIPM Is Configured as a 2WD Vehicle. Generic causes of P2067: Short to ground in the signal circuit, Faulty fuel level sender 'B', Corroded or shorted connector, Damaged wiring harness.
How much does it cost to fix P2067 on a Jeep?
Published repair estimates on Jeep range from $150 to $800 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
