SOURCE: volvo xc70 in limp mode 7 fault codes recorded d5

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.

2000 vw beetle 2.0 L, low level coolant light...engine mil code 1256


not the pump but air in the system or a broken wire to the coolant level sensor
that sensor at the top of the radiator tank has to be completely immersed in coolant or the circuit is broken and the light comes on
same effect id the wire to that sensor is broken in the insulation

1995 honda odyssey starting problems


Hello! in 1995 stored trouble codes used the On Board Diagnostic I software (OBDI)..Scanners will not work...The control unit LED can indicate any number of simultaneous component conditions by blinking separate codes, one after another...An instrument panel mounted indicator lamp will light and stay lit. If the lamp is on, or if a system malfunction is suspected even though the lamp is off, it is necessary to inspect the electronic control unit LED display. The LED display is on the ECM (ECU), which is located just below the RH side of the instrument panel. The indicator lamps operate whenever the ignition is On and a DTC is stored in the ECM (ECU) memory.
When an abnormality is detected the ECM (ECU) display blinks. The LED blinks a certain number of times, with the number of blinks indicating the number of the DTC. After the LED blinks a number of times there will be a two second pause and the LED will blink out the number of the next DTC..here are the codes..If there is a code send it to me...If there isn't a code I'll take it from there...guru.saailer

Flashing airbag light 4 blinks 6 blinks


This is a code 46 LH Crash Sensor - Not Mounted to Vehicle Properly. Often there is a poor contact on one of the wiring connectors. Some of the problems can happen from a poor connection where everything connects under the drivers side seat.
Here is a list of codes for the airbag light issues.

WHY IS THE SERVICE ENGINE LIGHT ON IN MY SATURN??


The Check Engine light will light when the ECU stores a trouble code.
Counting the Flashes
To retrieve trouble codes, turn the ignition key to the "on" position with the engine OFF.
The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.

My 95 jetta 2.0 temp light blinks even though I have replaced both the sensor and the overfill tank. Car is not over heating and the gauge reads normal. Connections all are clean and tight. How can I...


There is two sensors-blue for fuel mixture preparation & black with 4 pins for a gauge and overheating control.You told me that you has been change all sensors.Did you put new ones? Also check for engine coolant level sensor on a white plastic tank. there is not another reason for LED to blinking.

1995 Park Avenue heater A/C tempature reading flashes


one or more of your actuators is malfuntioning.  they ar eunder the dash.  I had a mechanic repair mine for about 400 bucks.  the dash needs to b removed and some very tight spots to work in.  the flashing is maybe caused from the sensor.  either outside air tempo sensor or inside. does it blink while showing the inside or ouside.  not exactly sure where the inside is, but the outside is in the center in front of radiator when u open the hood. black about the size of a tube of chap stick.

Hard start


DTC - 15 Engine coolant temp sensor error (low temp indicated)
This is an Diagnostic Trouble code using the OB1 which simply means the check engine light blinking in series at certain intervals.But my thinking says that if you are having trouble wuth any sensor , the ECU or PCU computer will read all kinds of things in error. Try replacing the TCS temperature control sensor.Only 96 and up have a OB2 Diagnostic system

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
