Dodge All models error codes
Codes
- C0031Error codeLeft front wheel speed sensor circuit fault. Failed sensor, damaged tone ring, or broken wheel harness wiring. Harness is vulnerable to abrasion near the ABS ring on Dodge trucks. Inspect harness; replace sensor if harness is intact
- C0034Error codeRight front wheel speed sensor circuit fault. Same as C0031 on the opposite side. On Ram 1500, right front sensor is a slightly more common failure due to routing near the exhaust. Replace sensor; inspect connector for corrosion
- C0036Error codeLeft rear wheel speed sensor circuit fault. Hub damage from off-road use or corrosion at the sensor mounting boss. Replace sensor; inspect hub condition before reinstalling
- C0051Error codeBrake pedal position sensor circuit fault. Failed brake light switch - most common cause on Durango and Grand Caravan. Disables traction control and stability control simultaneously. Replace brake light switch
- C0121Error codeABS valve solenoid circuit fault. Failed solenoid in ABS hydraulic modulator, wiring damage, or failing ABS module. Diagnose with ABS-capable scanner; replace modulator or module as indicated
- P0011Error codeCamshaft timing over-advanced, Bank 1. Stuck oil control valve or degraded oil. Check oil condition first; replace OCV or cam phaser if needed
- P0016Error codeCrankshaft/camshaft correlation fault, Bank 1. Stretched timing chain on 3.6L Pentastar past 100,000 miles; slipped reluctor on 5.7L Hemi. Confirm with live data before replacing sensors
- P0017Error codeCrankshaft/camshaft correlation fault, Bank 1 Exhaust. Stretched timing chain - when appears with P0016, confirms chain as cause rather than sensor
- P0036Error codeDownstream O2 sensor heater fault, Bank 1. Failed heater element inside post-catalyst sensor. Replace downstream O2 sensor; does not indicate converter failure on its own
- P0087Error codeFuel rail pressure too low. Failing fuel pump (common on 5.7L Hemi Ram past 150,000 miles), clogged filter, or leaking pressure regulator. Check pressure with a gauge before replacing pump
- P0100Error codeMAF sensor circuit fault. Dirty sensor, torn intake boot, or wiring issue. Clean MAF with dedicated spray first; replace if fault returns
- P0107Error codeMAP sensor voltage too low. Cracked vacuum hose or faulty sensor.
- P0113Error codeIntake air temperature sensor voltage high. Open circuit or disconnected connector at the airbox.
- P0117Error codeECT sensor voltage low. Faulty sensor or corroded connector. On 3.6L Pentastar, sensor connector is a known weak point.
- P0122Error codeThrottle position sensor voltage low.
- P0128Error codeCoolant temperature below thermostat regulating temperature. Thermostat stuck open - most common code on Charger, Durango, and Grand Caravan. Also causes poor heater output and downstream rich codes. Thermostat replacement resolves it in the majority of cases
- P0131Error codeUpstream O2 sensor low voltage, Bank 1. Exhaust leak upstream of sensor, failed sensor, or vacuum leak. Pressure test exhaust before replacing sensor
- P0135Error codeUpstream O2 sensor heater fault, Bank 1. Failed heater element inside the sensor. More frequent on 3.6L Pentastar past 120,000 miles. Replace upstream O2 sensor
- P0171Error codeSystem too lean, Bank 1. Vacuum leak, dirty MAF, low fuel pressure, or failing O2 sensor. On Ram 1500 3.6L, intake manifold gasket leaks are a documented cause. Smoke test for vacuum leaks first
- P0172Error codeSystem too rich, Bank 1. Stuck-open injector, failed O2 sensor, or ECT sensor fault. Often appears with P0128 when thermostat is stuck open. Start with thermostat if P0128 is present
- P0175Error codeSystem too rich, Bank 2. When appears with P0172, suspect a shared cause - MAF sensor, ECT sensor, or thermostat - rather than a bank-specific problem
- P0191Error codeFuel rail pressure sensor circuit performance. Inconsistent sensor signal rather than actual low pressure. Check wiring and connector; replace sensor if signal remains erratic
- P0201Error codeP0208 - Fuel injector circuit fault, cylinders 1-8. Failed injector, wiring damage, or failed PCM driver. On 5.7L Hemi, injector code alongside a misfire on the same cylinder strongly suggests a failed injector. Swap injector to confirm
- P0325Error codeKnock sensor circuit fault, Bank 1. Failed sensor, wiring fault, or corroded connector. On 5.7L Hemi, oil sludge from deferred changes can affect signal. Inspect connector first
- P0340Error codeCamshaft position sensor circuit fault, Bank 1. Failed sensor, wiring damage, or timing chain stretch. On 5.7L and 4.7L, chain wear is the common underlying cause. Check chain before replacing sensor
- P0365Error codeCamshaft sensor circuit fault, Bank 1 Sensor B. Failing exhaust cam sensor on 3.6L Pentastar or restricted VVT oil control valve from sludge. Clean OCV passages; replace sensor if passages are clear
- P0390Error codeCamshaft sensor circuit fault, Bank 2. On Hemi combined with P0340, confirms stretched timing chain beyond tensioner range. Timing chain kit replacement required
- P0404Error codeEGR valve position sensor performance. Carbon buildup on EGR valve - common on 6.7L Cummins diesel Ram. Clean or replace EGR valve; scheduled maintenance item on diesel models
- P0420Error codeCatalyst efficiency below threshold, Bank 1. Under 100,000 miles: failed upstream O2 sensor. Past 150,000 miles: converter at end of life. Running with misfire codes: misfires have damaged the substrate. Confirm O2 sensor function before replacing converter
- P0441Error codeEVAP system incorrect purge flow. Failed purge solenoid, cracked vacuum hose, or faulty fuel cap. Check fuel cap seal first
- P0443Error codeEVAP purge solenoid circuit fault. Failed purge solenoid on intake manifold.
- P0455Error codeEVAP system large leak detected. Loose or damaged fuel cap, cracked EVAP hose, or failed vent valve. On Ram, the EVAP canister vent valve near the fuel tank is a known failure point. Start with fuel cap; smoke test if cap is not the cause
- P0463Error codeFuel level sensor high. Sender out of range - part of the fuel pump module. Replace fuel pump module; standalone sender replacement is typically not available
- P0480Error codeCooling fan relay circuit fault. Failed relay, wiring issue, or faulty fan. On Charger and Challenger, fan relay is a known failure item. Replace relay first - inexpensive and straightforward
- P0506Error codeIdle RPM too low. Dirty throttle body, vacuum leak, or failed IAC on older models. Clean throttle body; check for vacuum leaks
- P0507Error codeIdle RPM too high. Vacuum leak or cracked intake boot. On 3.6L Pentastar, cracked boot between airbox and throttle body is a common cause. Inspect and replace boot
- P0532Error codeA/C refrigerant pressure sensor low. Low refrigerant charge or failed sensor. On Charger and Challenger, compressor shaft seal leakage is documented in warm climates.
- P0562Error codeSystem voltage low. Failing battery, corroded terminals, or failing alternator. On Ram 1500, fusebox cable connections corrode and cause intermittent drops. Load test battery;
- P0601Error codePCM internal memory checksum error. Internal PCM fault; sometimes resolves after battery disconnect. Can appear after jump-start voltage spike.
- P0622Error codeGenerator field control circuit fault. Failed alternator voltage regulator or wiring fault. Symptoms: erratic charging voltage, intermittent battery warning. Load test charging system;
- P0700Error codeTransmission control system malfunction. General code - the TCM has stored its own specific fault codes. Always appears alongside additional transmission codes. Read all stored codes; P0700 alone does not describe the fault
- P0711Error codeTransmission fluid temperature sensor performance. Sensor out of range or not responding to temperature changes. On NAG1 5-speed in Charger: common when fluid is degraded or transmission has been run hot. Replace fluid and sensor
- P0720Error codeOutput shaft speed sensor circuit fault. Erratic speedometer and poor shift scheduling. On 45RFE and 65RFE in Ram and Durango, output speed sensor is a known wear item. Replace sensor
- P0730Error codeIncorrect gear ratio. Low fluid level, failed solenoid pack, or slipping clutch pack. On ZF 8HP70 in later models, solenoid valve fault rather than mechanical wear. Check fluid level first
- P0740Error codeTorque converter clutch circuit fault. Failed TCC solenoid, contaminated fluid, or worn clutch plate. Highway shudder often precedes this code. Change fluid first; replace TCC solenoid if shudder persists
- P0750Error codeShift solenoid A circuit fault. Failed solenoid, wiring fault, or contamination in valve body. On 545RFE and 65RFE, solenoid pack replacement is a common higher-mileage repair
- P0841Error codeTransmission fluid pressure sensor circuit performance. Low fluid level, failed sensor, or internal valve body wear. On Ram with 66RFE, appears alongside shift quality complaints. Check fluid level first
- P0868Error codeTransmission fluid pressure low. Fluid loss, pump wear, or pressure regulator fault. Causes soft shifts and accelerated clutch wear. Do not continue driving - diagnose before further use
