…The check-engine light appeared with codes P018D and P018B. The vehicle subsequently experienced limp mode, loss of power, stalling, and severe shifting issues, especially with low fuel. Replacing the fuel pressure sensor did not resolve the codes or symptoms.
…unit was towed in by westway around 0100AM CHEK UNIT CODES P2635 PINPINT TEST NEED FUEL PUMP 02-12-24 Stalls over and over again Cause- Performed a DTC scan and found codes (P2635) fuel pump flow performance and (P018B) fuel pressure sensor performance.

…The vehicle has experienced fuel-system-related diagnostic trouble codes, including P2635 (Fuel Pump Flow Performance), P069E, and P018B. The high-pressure fuel pump has already been replaced, but the problem has continued. General Motors has also issued technical information addressing heat-related fuel system concerns involving this engine/platform. I have raised the issue with Chevrolet/General Motors and have GM case number XXX. Despite the recurring safety-related symptoms, I have not been provided with a permanent repair that makes the vehicle reliably safe to operate under the environmental conditions in which it was sold and is normally driven. My concern is not simply that the…
This is my 3rd complaint within 6 days. The entire electrical system in this 2017 Silverado 2500HD LT 6.6L appears to be committing suicide. First it was the Brake Controller Unit, Diesel Injector Connector (cylinder 7), P1050 DEF Level Sensor, U029E NOX Sensor Module 2 Communication Lost, U02A3 Lost Communication With Particulate Matter Sensor Module, and now P018B Code: Fuel Pressure Sensor "B". At what point will the manufacturer be held accountable for manufacturer defects on this vehicle (including the Dorman 603-009 Coolant Reservoir)? Every pump and sensor on the truck is failing within a week of the trailer brake controller failure? WHY is every wire harness on this vehicle (like so…

This has to be a recall may 2014 ford vehicles are having this issue along with the coolant leak. This needs to be recalled

Car suddenly got p018c & p018b codes along with (setc) notification while on freeway and continuously would go in and out of limp mode when accelerating or breaking which nearly caused me to crash. when arriving home I check my fuel pump relay and it looked burnt or overheated, I tried replacing sensors as well as relays but the problem remains whenever accelerating or breaking at low speed now, just without the check engine light.
P018B: questions drivers ask
What does code P018B mean?
P018B sits in the generic powertrain range (engine, transmission, fuel and emissions), but its SAE definition is not in CarHooq's list, so CarHooq shows only what owners reported. 10 owners reported it to NHTSA, most often for the Alfa Romeo Giulia (3), Chevrolet Tahoe (2), Chevrolet Camaro (1); their reports describe what happened.
Which cars get code P018B most often?
In NHTSA owner complaints, P018B is mentioned most for the Alfa Romeo Giulia (3), Chevrolet Tahoe (2), Chevrolet Camaro (1), across 8 models and model years 2014 to 2020. Popular models collect more reports because more of them are on the road.
Is there a recall for code P018B?
No NHTSA recall text names P018B directly. 5 recalls on the cars that report this code concern the same component owners name most (Fuel/Propulsion System); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P018B?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
How this page was made
CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of P018B. The code is in a generic range but its standard definition is not in CarHooq's list, so CarHooq shows only what owners reported. Nothing here is a diagnosis. More answers: the fault code FAQ. Data: NHTSA Office of Defects Investigation (public domain), retrieved November 9, 2026. How CarHooq reports are made.
