There are mainly two causes for you bmw x3:
The heater within the thermostat has failed - replace the thermostat
The wiring to the thermostat has failed - repair the loom
Without a working thermostat-heater, the engine performance will be reduced at high-throttle settings.

SOURCE: I HAVE A BMW X3

zjlimited_837.jpg

DTC P3242
Fault location: Cooling thermostat control circuit - signal high
Probable cause: Wiring, cooling thermostat

Where is your coolant temp. gauge reading at operating temperature? Does it look normal? Is your answer is YES, the only thing between the DME (Digital Motor Electronics) module and the fuse is the Characteristic Map Cooling Thermostat. This code was probably a faulty thermostat electrical resistance (think at changed a new thermostat housing and the heating element).

If you had a problem with the module or the fuse, it would throw a different code. But, it knows it's there and operating, just operating incorrectly. This leads right to the electrically heated thermostat.

I'd say go ahead and change the thermostat. Just make sure you get the whole assembly including the heated probe and everything. I'm not sure how they sell it and if it makes you feel any better, I'm basing all this on the other BMW user with this wrong.

Keep us updated.

SOURCE: I have a code P0108 Map/Baro Circuit High Input

the map/baro circuit could have an internal short suppling incorrect voltage to the wrong circuit.you need to check the voltages,ground,and return voltage at the sensor plug with it connected to the sensor with the key engine off and the car running to see if the sensor is getting the proper voltage and has a good ground,also check the plug itself as it could be the problem

Engine light on

It's really a DAEWOO car.+ Suzuki +GM.(good luck!)
with GM 2.0L L34 engines, common in USA.
wiki it and see the horror yet>?

P0107,

your map sensor is bad or dirty. (clean it , visual inspection, time....gunk in the vac port?)

or the PCM is confused, what does that mean?,
it means the vacuum is bouncing (bad cam timing or worse) and PCM can't know that and sees vacuum wrong.
IT CAN BE WRONG.
find a real ASE shop and avoid the zone.

here is the official page on this code
Trouble Code: P0107 (2.0L L4 VIN - Auto)
Manifold Absolute Pressure (MAP) Circuit Low Input


Trouble Code Conditions:
MAP: 5 kPa, 37.5 mmHg or less (Low pressure-High vacuums-Low voltage)

Possible Causes:

“Lg” circuit open or shorted to ground

“Or/G” circuit shorted to ground

MAP sensor malfunction

ECM malfunction

comment:
and engine vacuum IS wrong. (bouncing?)

Code p1652 on a 1996 pontiac grand prix does anyone know what it means the book for computer codes is incomplete

Trouble code P1652 means: Cooling Fan 2 Relay Control Circuit Malfunction

I would start by checking power supply to the cooling fans,making sure the coolant system is full,& using a scn tool to verify the proper operation of the cooling fan system.Here is some info to help you.

The Powertrain Control Module (PCM) controls the operation of the cooling fans. This is accomplished by providing a ground path for the cooling fan relay coils within the PCM. The relay contacts will close and complete the circuit between the fusible link at the battery junction block and the fan motors. Whenever there is a fan ON request both fans will be running.

Power for the fan motors is supplied through a fusible link at the battery junction block. Battery positive voltage is applied to the cooling fan relay contacts and coils. The cooling fan relays are energized when current flows through the relay coils to ground at the PCM. The cooling fan relay #1 control circuit is used for low speed cooling fan operation. The cooling fan relay #1 control circuit and the cooling fan relay #2 and #3 control circuit are both grounded for high speed fan operation. The cooling fan relay control circuits are monitored by the PCM. Before using the Electric Cooling Fans diagnostic tables be sure to perform the Powertrain On-Board Diagnostic System Check. If diagnostic trouble codes P1651 or P1652 are present, use the appropriate DTC diagnostic tables prior to performing Electric Cooling Fans diagnostics.

Important:
When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. It is important to perform the Powertrain On-Board Diagnostic System check prior to diagnosing the engine cooling fans.The PCM will complete the ground path for cooling fan relay #1 under any of the following conditions:
- When engine coolant temperature exceeds 105°C (221°F)
- When A/C is requested and ambient temperature is greater than 10°C (50°F)
- When A/C refrigerant pressure is greater than 190 psi (2 volts)

For high speed cooling fans operation, the PCM will delay control of the cooling fan #2 and #3 relays for 6 seconds. The 6 second delay ensures that the cooling fan electrical load will not exceed the capacity of the system. The PCM will complete the ground paths for cooling fan relays #1, #2, and #3 under any of the following conditions:
- When engine coolant temperature exceeds 113°C (235°F)
- When A/C refrigerant pressure is greater than 275 psi (2.9 volts)

If a problem that involves the low speed cooling fan relay control circuit (cooling fan relay #1 control) exists, DTC P1651 should set. If the problem affects the high speed cooling fan relay control circuit (cooling fan relay #2 and #3 control), DTC P1652 should set. A problem with the ECT sensor should set DTC P0117, P0118, P1114, or P1115. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis table. The Electric Cooling Fan Diagnosis table should be used to diagnose the PCM controlled cooling fans only if no DTC is set.
Hope this help to solve your poblem (remember rated and comment this help).

1988 Dodge Aries K 2.5L Engine Trouble and codes

CODE 14
Trouble Code 14 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally high readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operations among others. The thermistor used has a low resistance when hot, rising as the coolant cools. This error then, indicates a very low resistance in the CTS circuit.
CODE 15
Trouble Code 15 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally low readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operation, among others. The thermistor used has a high resistance when cold, lowering as the coolant warms. This error then, indicates a very high resistance in the CTS circuit.
CODE 33
Trouble Code 33 indicates that the Mass Air Flow (MAF) sensor is reporting more air is entering the engine than makes sense based on RPM and TPS. The MAF sensor produces a frequency output; around 30 Hz at idle to 150 Hz under acceleration. The frequency varies proportionally to airflow. The ECM monitors the frequency and thus determines airflow into the engine. Typical idle MAF is 5 to 7 grams per second.
