there is currently a recall being performed on altimas and there is also a updated crank position sensor check with your dealer for open recalls on your vehicle (its just a phone call away have your vin # ready (located on left bottom of windshield if your facing it from in front of vehicle it is on lower right side of windshield - also look on driver door jamb.

SOURCE: input/turbine speed sensor circuit

Your speed sensor, is located on top of the transaxle, near the starter. To access it, remove the battery, then remove the battery tray (4 10mm bolts). You will see wires coming from the lower oxygen sensor, and they snap into the bracket that holds the speed sensor in place. The actual speed sensor has a 2 wire clip on it, and is held in place by the bracket and a 10mm bolt.

SOURCE: I pulled the codes and here they are : C0036, C0035, C0040

Sounds like you need front wheel speed sensors. Replace the wheel bearings and sensors. May have an ABS unit fault, but more likely is both wheel bearings/speed sensors.

Location of the speed sensors on my 1999 ford explorer


Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

Service engine light is on and code P0526


The Powertrain Control Module (PCM) uses the cooling fan speed signal in order to determine the actual fan speed in relation to the desired fan speed. The PCM uses the cooling fan speed signal in order to reduce the cooling fan noise and in order to maintain the powertrain cooling requirements. The PCM supplies power and ground to the clutch hall effect sensor of the cooling fan clutch. The hall effect sensor returns a signal pulse through the speed signal circuit in response to the reluctor track, which is located inside the fan clutch. If during operation, the PCM detects a loss of the cooling fan speed signal, DTC P0526 will set
  • An inline connector could cause an intermittent DTC. Ensure to test for poor connections and pin retention at all inline connectors. Refer to system schematics for connectors and locations.
  • If the condition is not present, refer to Testing for Intermittent and Poor Connections.
  • Disconnect the harness connector of the cooling fan clutch from the shroud. Inspect the exposed wires between the harness connector and the tubing.
  • Inspect the cooling fan clutch harness in order to ensure that the clutch supply voltage circuit is not shorted to the following circuits:
  • The 5-volt reference circuit.
  • The cooling fan speed signal circuit.
  • The low reference circuit.
  • DTC P0526 will set if the engine is started without the drive belt ON.

you need the engine speed sensor. Ask the vendor where the exact location is. This is a foreign Car code.Volks wagon. Looked up the code and somebody else had the problem.

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
