DTC P0010600 – Manifold Absolute Pressure (MAP) / Barometric Pressure Range/Performance.

✅ Meaning of P0010600

This code indicates that the ECU sees MAP sensor readings not matching expected engine operating conditions or not correlating with the Barometric Pressure (BARO) sensor.
This is usually a Range/Performance issue — not “high or low input,” but values outside expected pattern.

✅ Common Causes

1. MAP sensor problems

Sensor contaminated with oil/carbon

Weak or failed MAP sensor

Incorrect voltage output

2. BARO sensor issues

Built into MAF in many vehicles

BARO reading does not match ambient pressure

3. Vacuum / Intake system issues

Intake manifold leaks

Split hoses / loose clamps

Leaking brake booster or PCV system

4. Wiring or connector problems

Open/short in MAP circuit

Poor ground

Water intrusion in connector

5. Engine mechanical issues

Timing problems

Low compression

Sticking throttle body

6. ECU internal fault (rare)

🧰 DIAGNOSTIC STEPS (Step-by-Step)

1. Scan live data

Check:

MAP at KOEO (Key On Engine Off)
Should read near ambient pressure (~95–101 kPa depending on altitude).
If MAP is far from this → sensor or BARO mismatch.

BARO reading
Compare BARO with MAP at KOEO.
Difference should be less than 3 kPa.

2. Check MAP sensor wiring

Use multimeter:

5V reference – Check for stable 5V supply

Ground – Should be less than 0.1V drop

Signal wire –
KOEO: ~4.0–4.5V
Idle: ~1.0–1.5V

If signal is stuck high/low or fluctuating → sensor/wiring fault.

3. Inspect for vacuum leaks

Check:

Manifold gasket

Intake hose cracks

PCV hose

Turbocharger piping (if turbo)

Brake booster vacuum line
Spray carb cleaner around leaks to confirm.

If MAP reading is high at idle (> 50 kPa) → vacuum leak.

4. Test the MAP sensor directly

Remove MAP and check for:

Oil contamination

Carbon blockage

Water damage

Clean with electronics cleaner and reinstall.

If no change → replace.

5. Inspect throttle body

Check for carbon buildup

Check electronic throttle actuation
A sticking throttle can cause wrong MAP values.

6. If BARO is part of the MAF sensor

Check:

MAF sensor wiring

Clean MAF sensor

Ensure no obstruction in air filter box

If BARO reading incorrect → replace MAF.

🛠️ Fix Summary

💥 MAP sensor clean/replace
💥 Repair vacuum leak
💥 Repair/replace damaged wiring
💥 Clean throttle body
💥 Replace MAF (if BARO fault)
💥 Reset ECU and perform road test.
