What P26F1 means
P26F1 is the opposite case to P26F0: the module commands starter relay A on, but the expected reaction never arrives, so the starter receives no power. Possible reasons are burnt or contaminated contacts, a coil that no longer pulls in, or a missing feed on the load side, for example a blown fuse or a loose battery cable at the relay. No maker documents P26F1 publicly. As reference points remain FCA, whose Jeep bulletins treat its two starter relays as separately monitored outputs and describe intermittent no-crank conditions, and GM, whose 2018 tables monitor the starter relay A driver. Because a dead relay looks like a dead starter, check whether the starter terminal receives voltage during cranking before replacing the motor.
P26F1 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P26F1
- Engine does not crank, or only after several attempts
- Check engine light
- No restart after an automatic stop
Common causes of P26F1
- Most likelyBurnt or dirty contacts in starter relay A
- PossibleBlown fuse or loose power cable on the load side of the relay
- PossibleRelay coil no longer pulling in
- Less likelyFeedback wire to the module interrupted
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P26F1 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| F1 | The exact fault in that area. |
What to do next
- Note P26F1 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P26F1
What does P26F1 mean?
P26F1 means "Starter Relay A Stuck Off". P26F1 is the opposite case to P26F0: the module commands starter relay A on, but the expected reaction never arrives, so the starter receives no power. It is a generic code, so it means the same on every make.
Is it safe to drive with P26F1?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P26F1 fail an emissions test?
Yes, it can. P26F1 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P26F1 to fix?
Difficulty: easy. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P26F1 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
