TIMING MARK

2005 Dodge Neon

Engine Mechanical problem
2005 Dodge Neon 4 cyl Front Wheel Drive Automatic 79891 miles

Hy! I own a 2005 dodge neon sxt and just recently my dad, while it was raining he tried to go over a wash and the car stalled. The next morning the car turned on fine and 2days later the " CHECK ENGINE" light turned on. We might think that while the water might have done the damage it could affected the timing belt and water could of caused it to slip on the timing. Anyways im trying to fix the problem by trying to find the TIMING MARK on the pulley itself but I cant find it. WHERE CAN I FIND THE TIMING MARK? PLS HELP

Checking and changing the timing belt is not a bad idea at this mileage

I don't think its the cause for the check engine light

u need to get the codes

u can do that by cycling the ignition key on off three times ending with key in the on position
read codes in the odometer area (P # ## #)

REPLY: thanks for your help I really appreciate it. The codes that come up are P0068 and P2074 and probable causes are 1) Check Engine for vacumm leak. 2) Check Engine condition and/or mechanical condition**Plugged exhaust or intake. 3) Trasnmission condition*this is why I asked about the timing*) If you have any advice pls let me know Thanks!

P0068-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION
When Monitored: With the engine running and no MAP Sensor or TP Sensor DTC's set.
Set Condition: The PCM determines a valid range in which the TP Sensor should be, at a given RPM/Load. The actual TP Sensor voltage is then compared to this value. If the TP Sensor voltage does not fall within the expected range within a predetermined time an error will be detected. Two Trip Fault.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
HIGH RESISTANCE IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
RESISTANCE TO GROUND IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
MAP SENSOR
HIGH RESISTANCE IN (K1) MAP SIGNAL CIRCUIT
RESISTANCE TO GROUND IN (K1) MAP SIGNAL CIRCUIT
HIGH RESISTANCE IN (K4) MAP GROUND CIRCUIT
PCM
TP SENSOR OPERATION
HIGH RESISTANCE IN TP SENSOR (K6) 5 VOLT SUPPLY CIRCUIT
RESISTANCE TO GROUND IN TP SENSOR (K6) 5 VOLT SUPPLY CIRCUIT

HIGH RESISTANCE IN (K22) TP SIGNAL CIRCUIT
RESISTANCE TO GROUND IN (K22) TP SENSOR SIGNAL CIRCUIT
HIGH RESISTANCE IN TP (K167) SENSOR GROUND CIRCUIT

As you see the two codes are the same
the main issue is the map sensor

P2074-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION - HIGH FLOW/VACUUM LEAK
When Monitored: Engine Running, during all drive modes.
Set Condition: If vacuum drops below 1.5 Hg with engine RPM greater than 2000 RPM at closed throttle.
