The definition of code P26B7 is “Coolant Bypass Valve C Control Circuit/Open.” This code indicates that your vehicle’s powertrain control module (PCM) or engine control module (ECM) has identified a problem with the vehicle’s Coolant Bypass Solenoid or Coolant Bypass Valve C, which helps reduce hot spots in the engine. This is technically an OBD-II generic powertrain code but is almost universally reported only in Ford vehicles, especially the Ford Escape.
More About Error Code P26B7
Coolant Bypass Valve C, usually a vehicle’s name for the coolant bypass solenoid valve, allows your powertrain control module (PCM) or engine control module (ECM) to control the coolant flow through the engine. The valve closes when the engine is cold, which prevents the coolant from flowing through the engine. However, when it warms up, this valve will open, which allows the coolant to flow and creates a more consistent operational temperature. When error code P26B7 comes up, the circuit controlling this valve or solenoid is open and malfunctioning.

What Are the Symptoms of a P26B7 Code?
The common symptom that you should expect with all P26B7 codes is that the check engine light will turn on. However, depending on the underlying cause of the P26B7 code, you might also see other problems within your engine. These problems may include decreased fuel economy, reduced engine performance, and increased emissions. Sometimes, you might also see engine overheating, depending on how severe the coolant issues are.
What Are Some Causes of a P26B7 Code?
This problem is usually due to a localized issue in and around the coolant bypass valve C. The most common causes include a faulty coolant bypass solenoid valve, damaged wiring and connectors through the coolant bypass solenoid valve circuit, problems with connector pins, loose wiring, electrical connectors, and other connection problems. You may also see this problem occasionally due to a low coolant level. Sometimes, a faulty PCM or ECM can also create the P26B7 code, which is extremely uncommon.
How Serious Is the P26B7 Code?
The P26B7 fault code is serious. It can result in serious engine damage if left untended over time. Any time your coolant can’t move throughout your engine, you’re looking at potential engine problems, ranging from misfires to an overheating engine to low fuel economy and much more. If you’re looking for a great reason to tackle the P26B7 code as soon as possible, low fuel economy can mean you’re spending more money on fueling your car if you don’t fix it.
Can I Still Drive with a P26B7 Code?
In many cases, you will physically be able to drive with the P26B7 code, as it’s fairly uncommon for it to create a no-start condition. However, driving at a higher engine load or speed, including driving with a trailer, uphill, or fast, can create engine performance issues and other problems. The more you drive with this code, the more likely you’ll experience engine damage.
How Easy Is It to Diagnose a P26B7 Code?
The problem with the P26B7 code is usually an issue with the coolant bypass valve and sometimes with the coolant bypass valve control circuit. That means there are few problems to check. But you must check for these problems, as replacing a part without checking can be expensive and won’t fix the core issue. Diagnostic tools help, but determining what’s happening in a faulty engine often requires technician service training. If you aren’t well-versed in the diagnostic process for the P26B7 code, it’s best to get an expert to help.
How Difficult Is It to Inspect a P26B7 Code?
Inspecting engine code P26B7 requires the correct tools: a diagnostic scanner, a digital volt-ohmmeter (DVOM), and a reliable source of vehicle information, which may include wiring diagrams, technical service bulletins, vehicle service manuals, visual inspections, and more. Additionally, because the Ford Escape P26B7 code is most common, you might need additional help if you’re getting this code in a vehicle that is not a Ford Escape. If you’re looking for help, talk to a certified mechanic who can ensure you get a fix without any common mistakes that an amateur technician might make.
Need Additional Help with Your P26B7 Code?
