P0198 Chrysler Sebring Iii Diagnostic Trouble Code
P0198 Chrysler Sebring Iii code definition:
P0198 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Chrysler Sebring Iii.
P0198 Chrysler Sebring Iii is triggered when the bank 1 camshaft position sensor doesn't match the signal from the crankshaft position sensor. There are two wires dedicated for each coil; one is battery feed which usually comes from the distribution center, and the other one for the coil driver circuit from the PCM. The PCM grounds or ungrounds the circuit to activate or deactivate the coil.
Symptoms
Symptoms of a P0198 Chrysler Sebring Iii diagnostic trouble code may include:
- Possible spark knock (detonation / pre-ignition)
- Poor fuel economy
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
- Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
- Defective ECU strategies or components will prevent proper regeneration

Common Misdiagnoses
- IC Circuit High Voltage Problem
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- PCM Stack Overrun Problem
Repair Processes :
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
Look at the plug wires to make sure they are not burnt or laying on the exhaust.
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
