P06EE code meaning
Engine RPM Output Circuit High
What P06EE means
The engine module turns the crankshaft signal into a cleaned-up square wave for the tachometer, transmission or body-builder modules – Saab's 1999 9-3, for example, sends two pulses per revolution, about 30 Hz at idle. P06EE means this output is too high, typically shorted to supply voltage, so it can no longer switch to ground; the driver may shut down for protection. It is the counterpart of P0654 (open circuit) and P06ED (low). CARB requires output circuits to be checked. No manufacturer document available to us uses this code; the description follows CARB, the component and P0654. The tachometer then reads nothing or full scale, and modules using the signal lose it, while the engine runs normally.
P06EE at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P06EE
- Tachometer shows nothing or full scale
- Other modules without speed signal
- Engine runs normally
Common causes of P06EE
- Most likelyOutput wire shorted to 12 V
- PossibleWrongly connected accessory (speed pick-up)
- PossibleReceiving device faulty
- Less likelyEngine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P06EE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| EE | The exact fault in that area. |
What to do next
- Note P06EE 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 P06EE
What does P06EE mean?
P06EE means "Engine RPM Output Circuit High". The engine module turns the crankshaft signal into a cleaned-up square wave for the tachometer, transmission or body-builder modules – Saab's 1999 9-3, for example, sends two pulses per revolution, about 30 Hz at idle. It is a generic code, so it means the same on every make.
Is it safe to drive with P06EE?
P06EE does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P06EE fail an emissions test?
P06EE is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P06EE to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P06EE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
