PCM will set a failure P0106 DTC when
The output signal of the MAP is stuck lower than enable conditions.
MAP sensor value is less than calculated (threshold) value for 2 min during acceleration and deceleration.
MAP signal changes over 10% with no movement of the Throttle Position Sensor (TPS) or accelerator pedal.
Item | Detecting Condition | Possible cause | |
DTC Strategy | Case 1 |
•
Monitor the MAP sensor's signal | 1. Connecting condition 2. Open or short to ground in power circuit 3. Open or short to ground in signal circuit 4. Faulty TPS 5. Faulty MAPS 6. Faulty PCM |
Case 2 |
•
PCM compares MAP signal range to an expected range based on engine speed and throttle position | ||
Case 3 |
•
This code detects a erratic signal change of the MAP | ||
Enable Conditions | Case 1 |
•
No Disabling Fault Present
•
Shutdown time greater than 20 minutes
•
Engine running | |
Case 2 |
•
Engine Coolant Temperature higher than (140°F) (Engine at operating temperature)
•
Engine Speed between 600 rpm and 3000 rpm | ||
Case 3 |
•
Engine running
•
l ΔAPS l less than 5%
•
Engine Speed higher than 800rpm | ||
Threshold value | Case 1 |
•
The difference between the signal at key-on and the signal at engine start less than 0.5 kPa (0.07 psi) | |
Case 2 | - Power Test
•
Altitude compensated MAP less than Calculated min. MAP data
•
Altitude compensated MAP greater than Calculated max. MAP data - Deceleration Test
•
Altitude compensated MAP less than Calculated MAP data | ||
Case 3 |
•
|MAPS stable –MAPS current| greater than10 % | ||
Diagnosis Time | Case 1 |

For 3 seconds out of 5 seconds | |
Case 2 |
•
Continuous (within 5min.) | ||
Case 3 |
•
- | ||
MIL On Condition |
•
NO MIL ON(DTC only) | ||
