ON-BOARD DIAGNOSTIC [LF]

01-02–9

Mazda MX-5

P0069 Manifold absolute pressure/atmospheric pressure correlation

• PCM monitors differences between intake manifold vacuum and atmospheric pressure. If the difference is

below –12 kPa {–90 mmHg, –3.5 inHg} or above 12 kPa {90 mmHg, 3.5 inHg} when the following conditions

are met, the PCM determines that there is a MAP sensor performance problem.

MONITORING CONDITION

— 12—15 s from when ignition switch is turned off.

— Intake air temperature is above -10°C {14 °F}.

— Engine coolant temperature is above 70°C {158°F}.

P0101 MAF sensor circuit range/performance problem

• PCM monitors mass intake air flow amount when the engine is running.

— If the mass intake air flow amount is above 37 l/s for 5 s and the engine speed is below 2,000 rpm with the

engine running, the PCM determines that the detected mass intake air flow amount is too high.

— If the mass intake air flow amount is below 4.4—59 l/s (The value depends on engine speed.) for 5 s and

the engine speed is above 1,000 rpm with the engine running and the throttle opening angle above 50 %,

the PCM determines that detected the mass intake air flow amount is too low.

P0102 MAF sensor circuit low input

• The PCM monitors input voltage from the MAF sensor when the engine running. If the input voltage is below

0.21 V, the PCM determines that the MAF circuit has a malfunction.

P0103 MAF sensor circuit high input

• The PCM monitors the input voltage from the MAF sensor when the engine running. If the input voltage is

above 4.9 V, the PCM determines that the MAF circuit has a malfunction.

P0107 MAP sensor circuit low input

• The PCM monitors the input voltage from the MAP sensor when intake air temperature is above –10 °C {14

°F}. If the input voltage is below 0.1 V, the PCM determines that the MAP sensor circuit has a malfunction.

MONITORING CONDITIONS

— Calculated load: 13—32 %

P0108 MAP sensor circuit high input

• The PCM monitors the input voltage from the MAP sensor when intake air temperature is above –10 °C {14

°F}. If input the voltage is above 4.9 V, the PCM determines that the MAP sensor circuit has a malfunction.

MONITORING CONDITIONS

— Calculated load: 13—32 %

P0111 IAT sensor circuit range/performance problem

• If intake air temperature is higher than engine coolant temperature by 18 °C {32.4 °F} for 1.2 s with ignition

switch on

, the PCM determines that there is a intake air temperature sensor circuit range/performance

problem.

*: Ignition switch on when 6 h or more has passed since the previous ignition switch off

P0112 IAT sensor circuit low input

• The PCM monitors the IAT sensor signal. If the PCM detects that the IAT sensor voltage is below 0.16 V, the

PCM determines that the IAT sensor circuit has a malfunction.

P0113 IAT sensor circuit high input

• The PCM monitors the IAT sensor signal. If the PCM detects that the IAT sensor voltage is above 4.84 V, the

PCM determines that IAT sensor circuit has a malfunction.

P0116 Engine coolant temperature circuit range/performance

• The PCM monitors the maximum value and minimum value of engine coolant temperature when the engine is

started and 5 min have been passed after leaving the vehicle 6 h or more. If difference between maximum and

minimum values of engine coolant temperature is below 6 °C {10.8 °F} the PCM determines that there is an

ECT circuit range/performance problem.

P0117 ECT sensor circuit low input

• The PCM monitors the ECT sensor signal at PCM terminal 2AH. If the PCM detects the ECT sensor voltage

below 0.2 V, the PCM determines that the ECT sensor circuit has malfunction.

P0118 ECT sensor circuit high input

• The PCM monitors the ECT sensor signal at PCM terminal 2AH. If the PCM detects the ECT sensor voltage is

above 4.58 V, the PCM determines that the ECT sensor circuit has malfunction.

P0122 TP sensor No.1 circuit low input

• If the PCM detects that the TP sensor No.1 voltage is below 0.1 V while the engine is running, the PCM

determines that the TP sensor No.1 circuit has a malfunction.

P0123 TP sensor No.1 circuit high input

• If the PCM detects the TP sensor No.1 voltage is to be above 4.9 V after ignition switch to the ON position,

PCM determines that TP sensor No.1 circuit has a malfunction.

P0125 Excessive time to enter closed loop fuel control

• The PCM monitors the ECT sensor signal at PCM terminal 2AH after engine is started while the engine is cold.

If the engine coolant temperature does not reach the expected temperature for specified period, the PCM

determines that it has taken an excessive amount of time for the engine coolant temperature to reach the

temperature necessary to start closed-loop fuel control.
