Question about 1997 Mercedes-Benz E-Class

1 Answer

Had evaporator coil replaced. Every since then light replacement signal, garage door opener, engine electronic light warning signal works and dashboard meters work off and on. I believe a wire is loose. What's the problem?

Your dash was taken apart to replace the coil. It is possible a connector was loosened during the job. If you can get to any of the parts that are intermittent, maybe you can trace their wires and see if there are any loose connectors along the way.

98 mercury villager no start , code P 1320


Here is the entire description for the code -

When is the code detected?When the ignition signal in the primary circuit is not sent to Engine Control Module (ECM) during engine cranking or running.

Symptoms- Engine Light ON (or Service Engine Soon Warning Light)

P1320 NISSAN Description The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit
Possible causes - Faulty power transistor unit built into ignition coil
- Ignition primary circuit is open or shorted (circuit to ignition coils)
- Ignition primary circuit poor electrical connection (circuit to ignition coils)
- Faulty ignition system condenser
- Crankshaft position sensor circuit

help.png Help with this Tech notes The most common cause that will trigger the P1320 code is the ignition coils, one or more ignition coils may have failed. Even tough the coils may be working OK, the resistance for one or more of the coils is greater or smaller that what the Engine Control Module (ECM) is expecting. Measuring the resistance with the coil out of the vehicle may not show any failures, usually the coil fails under heavy conditions (hard acceleration) or certain temperatures.

The P1320 code means that there is problem with the "Ignition Coil" or the wire to the ignition coil. For some models without individual ignition coils the Ignition Coil is inside the distributor and the distributor need to be replaced to fix the problem.

P1443 code problem. How do I fix this?


P1446 - EVAP Canister Vent Control Valve Close
EVAP canister vent control valve remains closed under specified driving conditions.

This solenoid valve responds to signals from the ECM. When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.

This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP Control System (Small Leak) diagnosis.

The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

About the possible causes that your must solved:
- EVAP control system pressure sensor and the circuit
- Blocked rubber tube to EVAP canister vent control valve
- EVAP canister vent control valve
- Water separator
- EVAP canister is saturated with water


Hope this helps.

P0352 code came up what might be the problem


P0352 - Ignition Coil B Primary/Secondary Circuit Malfunction
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

When is the code detected?
The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation

Possible causes
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or

Possible solution
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM


Hope helps with this (remember to rate this answer).

2002 ford escape 3.0L DTC P0305and P0306 what would you ck


P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.

Trouble code P0320 ignition/dist. engine speed input circuit


P0320 - Ignition / distributor engine speed circuit malfunction

The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Electronic Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall

When is the code detected?
The P0320 code is triggered when 2 successive erratic PIP pulses are detected.

Possible Causes:
- Loose wires/connectors
- Faulty Crank Position Sensors
- Arcing secondary ignition components (coil, wires and plugs)
- Low battery charge
- Powertrain Control Module

Possible Solutions:
- Resecure loose wire or connectors
- If battery charge is low, recharge or replaced battery
- Replaced crank position sensor
- Replaced starter motor

Toyota Camry 1991 door light stays on


Replace the door ajar switch that is defective, short answer. But the issue here is any of the doors can cause the problem, since in order to replace this tiny switch the door panel must be removed to access the door latch the smart thing to do is have the dealer scan the BCM (body control module) and see which switch is causing the problem. Cost will be about $300.00 depending on where you live
