1998 chevy lumina pcm ign fuse keeps blowing

I PULLED THESE CODES,P0102 AND P1676.P0102 TOLD ME TO CHANGE THE MASS AIRFLOW SENSOR,WHICH I DID.P1676 WAS THE EVAP,WHICH I CHECKED AND IT WAS GOOD.THEN I CHECKED THE UNDERHOOD ELECTRICAL CENTER AND FOUND THAT THE FUSE TO THE PCM ING WAS BLOWN.I PUT A NEW FUSE IN AND TURNED THE KEY ON,THE FUSE BLEW AGAIN.SO THEN I DISCONNECTED THE MAF SENSOR AND HEATED OXYGEN #11 AND #2 AND THE EVAP AND PUT IN A NEW FUSE,TURNED THE KEY ON AND THE FUSE STILL BLEW AGAIN.COULD YOU TELL ME ANYTHING ELSE TO DO?COULD IT BE THE COMPUTER?

    I have this same problem. Also in a 98 Lumina. Service Engine Soon light came on. First the code P0102 (mass air sensor) came up. Reset it. Then both P0102 and P1676 ( purge valve solenoid) codes came up. Checked the fuses and found PCM IGN fuse was blown. New fuse also blew when car was started.

    Mechanic disconnected each sensor one at a time and thought it was the oil pan Low Oil sensor causing the fuse to blow. We decided to try leaving the sensor disconnected. He said he ran the car for 15 mins. and the fuse did not blow.

    However...on the way home the service engine soon light came on again and the fuse is blown again.

Update: I took the car to a mechanic that specializes in auto electrics and he found that the wire that goes to the back oxygen sensor had chaffed through over the transmission and was shorting out and blowing the fuse. He repaired it and the car runs beautifully.

Have a 2001 pontiac aztec i change fuel pump but still giving problems put in the computer give me p0102 and p1189 replaced them still the same whats next


P0102 - The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The powertrain control module (PCM) uses the MAF sensor signal in order to provide the correct fuel delivery for a wide range of engine speeds and loads. A small quantity of air entering the engine indicates deceleration or idle. A large quantity of air entering the engine indicates an acceleration or high load situation. The MAF sensor has an ignition 1 voltage circuit, a ground circuit, and a signal circuit. The PCM applies a voltage to the sensor on the signal circuit. The sensor uses the voltage in order to produce a frequency based on inlet air flow through the sensor bore. The frequency will vary within a range of around 2,000 Hertz at idle to about 10,000 Hertz at maximum engine load. DTC P0102 will set if the PCM detects a frequency signal lower than the possible range of a normally operating MAF sensor.
Sounds like you need a mass air flow sensor , but take it to a ASE certified repair shop an have it check , instead of just replacing it.
DTC P1189
The engine oil pressure switch is a normally closed switch that opens with the proper oil pressure. With the ignition switch turned ON and the engine not running, the PCM should detect a low signal voltage input. With the engine running, the pressure switch opens, and the PCM should detect a high signal voltage input. The PCM tests the state of the engine oil pressure circuit with the ignition switch turned ON, and the engine turned OFF. If the PCM detects a high voltage input on the engine oil pressure signal circuit, DTC P1189 will set.

2003 Grand Am Has P0102


It is not an ECM/PCM problem.
P0102 - Mass or Volume Air Flow Circuit Low Input
Possible causes- Faulty mass air flow sensor
- Dirty mass air flow sensor
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor

I recently had problems with my 2005 Mazda MPV stalling. I came to this great site and changed the IAC and it stopped stalling. But 2 days later my check engine light came on. The codes are P2197 P2195...


The descriptions for your codes are:
P2197 - H02S (RF) signal stuck lean
P2195 - H02S (RF) signal stuck lean
P2187 - Fuel System too lean at idle
P0102 - MAF circuit low input

Essentially what's happening is that your MPV is running too lean when at idle. Too much air and not enough fuel. As you speed up - it forces more air into the system which alleviates the problem.

Examine your mass airflow sensor. It should be completely clean - no fuzzies on it at all. If so - purchase some mass airflow sensor cleaner to clean the sensor. ONLY USE THE PROPER CLEANER TO AVOID DAMAGING THE SENSOR. Disconnect the battery to reset the system and turn off check engine light.

Otherwise you will need a scan tool to look at the voltages being supplied to/from the PCM for each of the Heated Oxygen Sensors and the Mass Airflow Sensor to determine which part is creating the problem.

P0102 and p1676 code active after replacing intake manifold gasket. replaced m.a.f but codes are both still active, voltage is good at maf and pins are tight. any suggestions?


IF YOU REPLACED MAF SENSOR YOU NEED A CODE SCANNER TO ERASE THE TROUBLE CODE.MAKE SURE MAF SENSOR ELECTRICAL CONNECTOR SEAT IN PLACE GOOD.

I get codes P0102 and P1128. My mechanic says I need to put a new mass air flow sensor on and it will take care of the problem. Is this correct?


This could very well be correct I believe code P0102 is the mass airflow circuit low input. P1128 should be a lean code.

I would first try cleaning your mass airflow sensor with a carb or throttle body cleaner, they have a tendency to get dirty and not read correctly.

Check engine code p1676


P1676 99-00 FPTDR signal line failure. Check connections between PCM and ABS/TCS control unit. If wires are good replace ABS/TCS Control unit. If it doesn't fix replace PCM.

Reset the code and see if it comes back.

Check engine light code p1676 Chevy lumina Ltz


Trouble Code: P1676 (3.8L V6 VIN K Auto)
Evaporative Emission (EVAP) Purge Solenoid

Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Conditions for Setting the DTC.
  • The ignition is on.
  • An improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
  • The above conditions are present for at least 30 seconds.

Possible Causes:
  • Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
  • Damaged harness.
  • Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition on and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.

Code p0102 chevrolet lumina 1998


Code P0102 means: Mass Air Flow (MAF) Circuit Low Input

I ran a Diagnostic on my 1998 chevy venture mini van and here are the codes that came up, P0102, P0134. What does this mean? I have already replaced the following, fuel pressure regulator, both crankshaft...


the 2 codes are

P0134 02 Sensor Circuit no activity Detected (bank 1 sensor 1)
first check your fuses check the wiring to the sensor(the sensor is on the exhaust in front of the engine-open the hood and look down) if the fuses and the wiring look good replace the O2 sensor there are 2 types of sensors original equipment(oe) style and universal the oe style has a connector you just plug in, the universal you have to hard wire in

the 2nd code is Mass Air Flow (MAF) Circuit Low Input
check the wireing, make shure theres a good connections
you said that you already replaced this sensor so im going to recomend that you go after the other code first

deal with the oxygen sensor then reset the computer and see what codes come back
