Jeep code 34


shoe drops, does it run?
97 is OBD2 in usa, so why not do a real scan, the blink codes do NOT tell all going on.
you could RTM here, read the manual here, the FSM.

1994 mercury airbag code 34


You can't disable the system to turn the light off. The system is disabled when the light is on.
Code 34 is for the driver side bag circuit, which could be several different issues. I never recommend car owners working on SRS but you can buy a shop manual and give it a try if you like.

Code 34 and 51


Code 34 is for the MAP sensor voltage being low which means the sensor is unplugged or faulty. Code 51 is for a problem with the memory chip inside the computer.
If the engine computer is failing it could set the code 34 even if nothing is wrong with the MAP sensor.
The computer and MAP sensor would need to be checked out.

Engine shut off willnot crank after heating up geting code 34


DTC - 34 MAP Sensor Circuit Error (Signal Low Indicating High Vacuum)

The ECM uses the Manifold Absolute Pressure (MAP) sensor as an indication of engine load. High voltage would indicate low engine vacuum and higher engine load. Low voltage would indicate high engine vacuum and lower engine load. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Fault Code Description:
* 34 - MAP sensor circuit error (signal low indicating high vacuum)

Symptoms:
* Poor engine performance
* Engine running lean (not enough fuel, hard starting, lack of power)

Common Problems:
* GM MAP sensors do not commonly fail
* Due to erratic engine vacuum, other engine performance problems can cause a code 34 to set


Good luck (remember to rate this answer).

I have a 1995 isuzu pickup it giving me error codes 15 and 34 and I've already been to 3 repair shops and can't get it fixed can you give me some help


I have the manual for my 93 rodeo and code 15 says ENGINE COOLANT TEMPERATURE SENSOR-SENSOR SIGNAL SHORTED, GROUNDED OR OUT OF RANGE. Check your coolant sensor by the water neck-it sends a signal to your dash gauge (coolant temp)
Code 34 my book has 2 symptoms- if its a 3.1 liter engine it says MAP SENSOR-SIGNAL VOLTAGE LOW-CHECK INCORRECT IDLE SPEED, VACUUM LEAKS, LOOSE AIR DUCT, MAP SENSOR CIRCUIT
If its NOT a 3.1 liter engine, then code 34 is EGR TEMPERATURE SENSOR CIRCUIT-SHORTED

Hope this helps.

Car keeps dying


Trouble Code 33 and 34 are the MAF/MAP Sensor Circuit. It sounds like you've replaced that sensor already. Did you also have the code 34 before putting in the new sensor?
Or did this code start after it's replacement? Any other codes appearing?

Troubleshooting it would depend if it has the Speed Density Update. The dealer should be able to provide that info.

Here's your fault code list:

13 oxygen sensor circuit 14 coolant temp sensor circuit (high temp) 15 coolant temp sensor circuit (low temp) 21 throttle position sensor (TPS) circuit (high signal) 22 throttle position sensor (TPS) circuit (low signal) 23 manifold air temp (MAT) circuit (low temp) 24 vehicle speed sensor (VSS) circuit 25 manifold air temp (MAT) circuit (high signal) 31 wastegate solenoid electrical circuit 32 exhaust gas recirculation (EGR) circuit 33 mass air flow (MAF) circuit (gm/sec high) 34 mass air flow (MAF) circuit (gm/sec low) 41 cam sensor circuit 42 C3I EST or bypass circuit failure 43 electronic spark control (ESC) circuit 44 oxygen sensor circuit (lean exhaust) 45 oxygen sensor circuit (rich exhaust) 51 PROM error 52 calpak error 55 ECM error
